Documentation & Release Management

  • nexus-staging-maven-plugin 1.7.0 - Essential plugin for automated Maven Central deployment via OSSRH

Build & Testing

  • maven-assembly-plugin 3.6.0 - Creates fat jar with all dependencies (16 MB) in ~5 seconds, full Java 21 compatibility
  • Docker-based integration tests - Testcontainers support for OS-independent testing (30 total: 29 passing, 1 skipped)
    • DockerSQLiteIntegrationTest - 7 tests for SQLite persistence, concurrency, large datasets
    • DockerDiskPersistenceIntegrationTest - 8 tests for disk persistence, compaction, WAL mode
    • DockerOffHeapPersistenceIntegrationTest - 8 tests for off-heap memory, container limits, concurrent access
    • DockerCompositePersistenceIntegrationTest - 7 tests for multi-tier persistence (6 passing, 1 skipped)
    • Tests run in isolated Alpine Linux containers with mounted volumes and memory limits
    • Real filesystem I/O, native memory, and multi-tier architecture testing
    • Known Limitation: testCompositePersistence_AllThreeLayers skipped due to StackOverflow when combining DiskPersistence + OffHeapIndex on same primary key (SQLite recursion issue)

    • Email updated to maintainer's contact
  • License header template - Updated src/etc/header.txt to use variables (${owner}, ${year}) for dynamic substitution

Dependency Updates (2025-12-17)

  • ByteBuddy - Updated from 1.9.10 to 1.14.11 (Java 21 bytecode support, class file version 65)
  • EqualsVerifier - Updated from 3.15.4 to 3.16.1 (Java 21 compatibility, fixes class file major version 65 error)
  • SQLite JDBC - Updated from 3.42.0.0 to 3.45.0.0 (CVE-2023-32697 security fix, ARM64 Mac support)
  • Kryo Serialization - Updated from 4.0.0 to 5.0.0-RC1 (Java 21 support, modern serialization)

Fixed

Test Compatibility Issues

  • EqualsVerifier compatibility - Fixed "Unsupported class file major version 65" error in QueriesEqualsAndHashCodeTest
  • SQLite native library - Fixed ARM64 Mac compatibility (resolved "No native library found for os.name=Mac and os.arch=aarch64" error)
  • Lambda type erasure - Fixed "Could not resolve sufficient generic type information" in DiskSharedCacheConcurrencyTest
  • ReflectiveAttribute equality - Fixed reflexivity test by suppressing Warning.REFERENCE_EQUALITY for intentional field comparison
  • Docker test logging - Configured SLF4J with Simple Logger to eliminate "Failed to load StaticLoggerBinder" warnings

Removed

Build Configuration

  • maven-shade-plugin - Commented out due to infinite loop issue on Java 21, replaced with maven-assembly-plugin
    • Shade plugin was hanging indefinitely during dependency analysis phase
    • Assembly plugin provides equivalent fat jar creation without relocation (acceptable for most use cases)

Security

  • CVE-2023-32697 - Fixed by updating SQLite JDBC from 3.42.0.0 to 3.45.0.0
    • Severity: Moderate
    • Impact: Potential security vulnerability in SQLite JDBC driver
    • Resolution: Upgraded to patched version 3.45.0.0
