This test runs fine in a normal test, but fails when run as a @NativeImageTest. It's in Kotlin, but it shouldn't matter.

@NativeImageTest
class ProjectResourceTestIT : ProjectResourceTest()

The normal JVM test it inherits from is:

@QuarkusTest
@TestInstance(TestInstance.Lifecycle.PER_CLASS)
@QuarkusTestResource(H2DatabaseTestResource::class)
class ProjectResourceTest {

    @Test
    fun testProjectsEndpoint() {
        given()
            .`when`().get("/projects")
            .then()
            .statusCode(200)
            .body(`is`("[]"))
    }
}

and h2 is pulled in by doing this:

    implementation("io.quarkus:quarkus-jdbc-h2")
    testImplementation("io.quarkus:quarkus-test-h2")

I couldn't find anything in the issues or discussion about this....how do folks do integration tests w/ H2 in Native Integration Tests?

Here's the rest of the stack trace:

Very interesting. Could you upload a small sample so I can check?

FYI, adding the H2DatabaseTestResource annotation to the native test didn't help either:

@NativeImageTest
@QuarkusTestResource(H2DatabaseTestResource::class)
class ProjectResourceTestIT : ProjectResourceTest()

Thought it might have been because ProjectResourceTestIT didn't inherit the annotation from the ProjectResourceTest...

Also tried the simplest test:

@QuarkusTest
class SimpleTest {
    @Test
    fun testNothingUseful() {
        Assertions.assertEquals(true, true)
    }
}

with

@NativeImageTest
class SimpleTestIT : SimpleTest()

which gives the same null pointer exception.

@kenyee @geoand created a PR #23146 to fix the issue. It will be part of the upcoming 2.7.0.Final.

@gsmet tested the above repro app with 2.7.0.Final and 2.7.1.Final and the error is still there.

ProjectResourceTestIT > testProjectsEndpoint() FAILED
    java.lang.IllegalStateException at LauncherUtil.java:82

2.7.1. also has an OOM error building the jar unless you add this to gradle.properties to adding a larger heap might be a good idea to default in gradle.properties:


org.gradle.jvmargs= \
    -Xms2g \
    -Xmx12g \
    -Dkotlin.daemon.jvm.options=-Xmx2g \
    -XX:SoftRefLRUPolicyMSPerMB=0 \
    -Dfile.encoding=utf-8 \

Better ping @geoand as he looked at the issue.

Not sure about the OOM. It's while building a native executable?

I'll have a look tomorrow

Yes. "./gradlew check" runs native integration tests so it has to build it. No need for extra mem in 2.7.0.Final, but needed in 2.7.1.

We upgraded to GraalVM 21.3.1 in 2.7.1.Final so that might be related to it.

Any chance you can add a reproducer project? I don't see where the NPE could be thrown

@geoand the reproducer is attached above...just change the Quarkus version to the latest.

I don't get a NPE when running the tests.

🤔 I grabbed the same file, put it into a separate directory, changed the gradle.properties to use 2.7.1.Final and added the JVM args and ran "./gradlew check" and still got the error.

> Task :testNative

ProjectResourceTestIT > testProjectsEndpoint() FAILED
    java.lang.IllegalStateException at LauncherUtil.java:82

1 test completed, 1 failed

Also tried a ./gradlew clean first, but that shouldn't matter because the zip didn't include the build folder.
Now the question is why our environments are different. 🤔

This is what I'm using for the JVM

java -version                                           
openjdk version "11.0.13" 2021-10-19
OpenJDK Runtime Environment GraalVM CE 21.3.0 (build 11.0.13+7-jvmci-21.3-b05)
OpenJDK 64-Bit Server VM GraalVM CE 21.3.0 (build 11.0.13+7-jvmci-21.3-b05, mixed mode, sharing)

./gradlew dependencies shows quarkus 2.7.1:

compileClasspath - Compile classpath for compilation 'main' (target  (jvm)).
+--- io.quarkus.platform:quarkus-bom:2.7.1.Final

For anyone else who might run into an error with integration tests, run gradle/maven with debug logging and you might see something like this:

2022-02-20T11:38:48.251-0500 [DEBUG] [TestEventLogger]     One or more configuration errors have prevented the application from starting. The errors are:
2022-02-20T11:38:48.251-0500 [DEBUG] [TestEventLogger]       - SRCFG00011: Could not expand value QUARKUS_DATASOURCE_PASSWORD in property quarkus.datasource.password

I had set up
%prod.quarkus.datasource.password=${QUARKUS_DATASOURCE_PASSWORD}
in application.properties but the env var wasn't set when running the test.

and the integration test uses the prod environment settings.

but this manifested in the "./gradlew testNative" output as an error like this:

> Task :testNative

ProjectResourceTestIT > testProjectsEndpoint() FAILED
    java.lang.IllegalStateException at LauncherUtil.java:82

1 test completed, 1 failed

because of the parsing of the error log stacktrace which doesn't take into account the TestEventLogger messages:
