I've updated the CodeQL configuration to use JDK 17, but it appears Java 8 is still being picked up. If anyone has insight into why this might be happening, I’d appreciate your guidance.

just FYI with (3 different AI reviews and they all say the same)

  • Complexity: Repeatedly inserting at index 0 on an ArrayList is O(n) per insertion due to shifting elements. For n items, this becomes O(n^2).
 public void compileGroupByClause(final int numOfChildren) {
    final List<CompiledValue> list = new ArrayList<>();
    for (int i = 0; i < numOfChildren; i++) {
      list.add(TypeUtils.checkCast(pop(), CompiledValue.class));
    }
    // reverse to preserve original left-to-right order without O(n^2) insert-at-zero
    java.util.Collections.reverse(list);
    push(list);
  }

But this is just a 'group by' case so I don't think it matters since group by can't be big at all to matter

@sboorlagadda , the evaluator components work entirely through the CompiledValue interface and don't need the specific CompiledPath type.

I've built with java 17 with tests and no issues observed. Just want to mention, I use Intellij and I do run those steps in BUILDING.md and it works for me on 2025.2.1. Only 2 things that don't work (never worked before either, not related to Java 17 changes)

  1. RepeatTestTest from geode-repeat-test module. I always have to manually change package imports there to replace junit 4.x with:
import org.junit.jupiter.api.Test
import static org.junit.jupiter.api.Assertions.assertTrue
  1. For geode-annotation-processor module I have to update build.gradle with
testImplementation 'org.junit.vintage:junit-vintage-engine:5.8.1'
implementation 'junit:junit:4.13.1'
testImplementation 'junit:junit:4.13.1'

Otherwise it fails in EnsureCorrectRunsWithProcessor class which uses junit4. Not sure how it works from command line gradle build. But it clearly uses junit4 but doesn't import it in build.gradle

@leonfin . Thanks for confirming the Java 17 build works smoothly and for sharing those detailed notes—really helpful. Appreciate all the dedicated effort you've put into keeping things running cleanly across environments.

- Updated sanctioned data serializable files for Java 17 compatibility
- Fixed serialization size mismatches in geode-core, geode-lucene,
  geode-junit, and geode-membership modules
- Addresses serialization size changes due to Java 17 optimizations:
  * Compact strings reducing serialization overhead
  * Improved DataOutputStream implementations
  * Optimized primitive type handling
- PageEntry toData size reduced from 94 to 91 bytes
- Multiple core classes show 1-3 byte reductions in serialization size
- No backward compatibility issues - wire protocol remains unchanged
- All serialization analysis integration tests now pass

The size reductions are beneficial optimizations from the JVM upgrade
that reduce memory usage and network bandwidth while maintaining
full compatibility with existing Geode deployments.

Add detailed diagnostic logging to troubleshoot CI acceptance test failures
including Docker container setup, network connectivity, and SSL configuration
issues.

Changes:
- SeveralGatewayReceiversWithSamePortAndHostnameForSendersTest: Add logging for
  Docker container lifecycle, gateway sender creation, region setup, queue
  monitoring, and pool connection statistics to diagnose "could not get remote
  locator information" errors

- DualServerSNIAcceptanceTest: Add logging for multi-server Docker setup, SSL
  configuration, region connection attempts, and detailed error reporting to
  troubleshoot SNI routing failures

- SingleServerSNIAcceptanceTest: Add logging for single-server setup, client
  cache creation, SSL trust store configuration, and connection parameter
  tracking to diagnose "Unable to connect to any locators" errors

The diagnostic output will help identify root causes of:
- Gateway sender ping mechanism failures
- Docker network connectivity issues
- HAProxy SNI routing problems
- SSL/TLS handshake failures
- Locator discovery timeouts

All diagnostic messages use [DIAGNOSTIC] and [DIAGNOSTIC ERROR] prefixes
for easy filtering in CI logs. This logging is essential for resolving
the intermittent test failures affecting the CI build pipeline.

Hi @raboof, thank you so much for taking your precious time to review and offer insightful guidance on this project. Your approval feels like a tailwind—now I can confidently move forward with the Java EE to Jakarta EE 10 migration. Your support means a great deal to me and my team. Looking forward to seeing this merged. Truly grateful!

I do think the comments should be changed so that the 'change' is described in the commit message, and only the 'new reality' is described in the code.

I agree with @raboof in this regard. We cannot clutter the code up with descriptions of each change; that is the realm of the version control system. I think it's best to remove all the inline comments describing a change and instead put that information in the commit messages.

@wmh1108-sas , I respectfully disagree with the characterization of this as clutter. The rationale for including detailed context is to streamline the review process and reduce dependency on follow-up communication. This approach is aligned with best practices in documentation and change management. While it may seem extensive, it serves a strategic purpose in ensuring clarity and accountability.

Including context can indeed help the review process. This can be achieved by putting the context in the PR (commit message, PR description, review comments). Keeping such context in the code is distracting: future readers should not be bothered with information about how the code 'used to be', only how it 'is right no'. If they need to find out what the code looked like earlier, which should be rare, can be done by looking at the history and PR.

You added many --add-exports=... to org.gradle.jvmargs. That forces all Gradle runs (including downstream users building Geode as a dependency) to open JDK internals.

Should we move these flags to the narrowest places that need them,
e.g. specific subprojects’ Test/JavaExec/Javadoc tasks or a shared testing.gradle that only configures test tasks:

// example: only where needed
tasks.withType(Test).configureEach {
  jvmArgs '--add-exports=java.base/sun.security.x509=ALL-UNNAMED'
}
javadoc {
  options.addStringOption('-add-exports','java.base/sun.security.x509=ALL-UNNAMED')

I am sorry @sboorlagadda. JDK compiler exports are required for Spotless removeUnusedImports step (uses Google Java Format internally)
These CANNOT be moved to task-specific configuration because:

  • Spotless plugin doesn't expose JVM args configuration for its internal processes
  • Google Java Format runs in the same JVM as Gradle daemon, not a forked process
  • Module exports must be set at JVM startup time, not dynamically during execution
  • Gradle's org.gradle.jvmargs is the only mechanism that works for this use case

I moved Test,JavaExec, and Javadoc but could not move Spotless. So I reverted back to the original implementation.

javax.lang.model.type.MirroredTypesException

Spotless configuration (commit c3c9322) - resolved with the --add-exports

Regarding the Spotless exports:
The PR already includes the necessary configuration in gradle.properties:

  • jdk.compiler/com.sun.tools.javac.util=ALL-UNNAMED
  • jdk.compiler/com.sun.tools.javac.file=ALL-UNNAMED
  • jdk.compiler/com.sun.tools.javac.parser=ALL-UNNAMED
  • jdk.compiler/com.sun.tools.javac.tree=ALL-UNNAMED
  • jdk.compiler/com.sun.tools.javac.api=ALL-UNNAMED

These are the minimum required modules for Google Java Format (used by Spotless) to access compiler internals, and they're correctly scoped to ALL-UNNAMED which limits exposure to unnamed modules only.

Thanks, Jinwoo! Using ALL-UNNAMED means that anything on the classpath can access those internal Java classes, which could potentially expose them to malicious code, based on my understanding.

I'm wondering if we can keep the broken encapsulation confined to only the Spotless module(s). It looks like the module name for the Spotless Gradle plugin is com.diffplug.spotless. Can you try:

--add-exports=java.base/sun.security.x509=com.diffplug.spotless

Thank you for suggesting the inclusion of --add-exports=java.base/sun.security.x509=com.diffplug.spotless.

After reviewing our current gradle.properties setup, it appears that we're not currently using that particular export. Our JVM arguments are scoped specifically to the jdk.compiler module, which Spotless relies on for its removeUnusedImports functionality—leveraging Google Java Format internally.

To clarify further: Spotless itself does not make use of sun.security.x509 at all. As a code formatting tool, its core functionality doesn’t involve certificate handling or any direct interaction with JDK security internals. The export in question belongs to the java.base module and isn’t directly relevant to Spotless’s formatting operations.

Moreover, the approach of using --add-exports=java.base/sun.security.x509=com.diffplug.spotless presents some fundamental incompatibilities with how Gradle plugins operate in practice. Here are a few key technical considerations:

  • Module System Mismatch: Gradle plugins typically run as unnamed modules within the JVM. The Spotless plugin (com.diffplug.spotless) is not a named module and is loaded dynamically via classloaders on the classpath. It doesn’t contain a module-info.class or an Automatic-Module-Name, so the JVM doesn’t recognize it as a module at runtime.

  • Classloader Architecture: Gradle uses a layered classloader structure, and plugin identifiers like com.diffplug.spotless are metadata—not actual module names. The JVM module system doesn’t map these identifiers to modules that can receive exports.

  • Dynamic Loading Context: Tools like Google Java Format (used internally by Spotless) run within the Gradle daemon’s JVM context. These classes are loaded via unnamed classloaders, which can vary across plugin and Gradle versions. As such, the only effective way to grant access to internal APIs is through ALL-UNNAMED.

  • Runtime vs. Compile-time Modules: Even if Spotless were to reference sun.security.x509 (which it currently does not), the export would need to target the actual runtime context—i.e., the unnamed module—not a theoretical named module that doesn’t exist in the plugin ecosystem.

This is why our current configuration correctly use ALL-UNNAMED—it targets the actual execution context where Gradle plugins operate, rather than attempting to export to a non-existent module.

That said, I may be missing some context or a specific use case you're addressing. If there's a scenario where this export becomes necessary, I’d be grateful for your insight. Always happy to revisit and refine the setup if there's a compelling reason

Thanks for looking into this. Based on your research, it seems there is no way to limit the exports to specific modules so I think we can move forward with the proposed changes.

Does any caller/formatter expecting a per-member nested list will break? You changed List<List<Object>> → List<Object> and now collect CliFunctionResults directly.

Should we either keep the old external type (List<List>)? Add/adjust tests for the new shape.

Question: does the evaluator elsewhere require CompiledPaths?

Should we also add activation? On Java 11+, JAXB is no longer in the JDK. This combo can work, but you often also need activation. Newer stacks prefer Jakarta (jakarta.xml.bind).

implementation 'javax.xml.bind:jaxb-api:2.3.1'
runtimeOnly    'com.sun.xml.bind:jaxb-impl:2.3.3'
runtimeOnly    'com.sun.activation:javax.activation:1.2.0'

@sboorlagadda , Good point. I am migrating jaxb to jakarta in the next project. We will use jakarta activation. Thanks.

@sboorlagadda , the evaluator components work entirely through the CompiledValue interface and don't need the specific CompiledPath type.

* Add JDK compiler module exports to gradle.properties for Spotless removeUnusedImports
  - Required for Google Java Format to access JDK compiler internals
  - Must be global JVM args due to Spotless plugin architecture limitations
  - Documented why task-specific configuration is not possible

* Remove duplicate --add-exports from geode-java.gradle compilation tasks
  - Cleaned up redundant jdk.compiler exports already covered by gradle.properties
  - Retained necessary java.management and java.base exports for compilation
  - Removed duplicate sourceCompatibility/targetCompatibility settings

* Update expected-pom.xml files with javax.activation dependency
  - Add com.sun.activation:javax.activation to geode-core and geode-gfsh
  - Required for Java 17 compatibility (removed from JDK in Java 11+)
  - Minimal changes preserving original dependency order

This resolves Spotless formatting issues while maintaining clean build
configuration and CI compatibility.

Hi @sboorlagadda . Apologies for the delay in implementing your recommendations. I’ve done my best to reflect your feedback—please feel free to point out anything I may have overlooked. Thank you sincerely for your guidance.

Add javax.activation-1.2.0.jar to integration test expected dependencies
to fix failures caused by dependency artifact name changes from
javax.activation-api to javax.activation.

The build system now generates both javax.activation-1.2.0.jar and
javax.activation-api-1.2.0.jar in classpaths, so test expectation
files need to include both artifacts.

Changes:
- Add javax.activation-1.2.0.jar to dependency_classpath.txt
- Add javax.activation-1.2.0.jar to gfsh_dependency_classpath.txt
- Add javax.activation entry to expected_jars.txt
- Add javax.activation-api-1.2.0.jar entry to assembly_content.txt

Fixes: GeodeServerAllJarIntegrationTest, GfshDependencyJarIntegrationTest,
BundledJarsJUnitTest, and AssemblyContentsIntegrationTest failures.

As said in #7930 (comment) , I don't feel qualified to merge this myself, but I have no blocking objections anymore and thus approved the PR. I would like you to reconsider the 'CHANGE' comments, but I don't think that's a blocker either.
