Graal: [native-image] Attempt to build native image that uses logback fails

[NAJ10]

I have put together a minimal example of a scala project built using sbt that uses logback that fails to compile to a native image. See the attached tar.gz file.

The error encountered is
[error] Fatal error: com.oracle.svm.core.util.VMError$HostedError: java.lang.NoClassDefFoundError: Lorg/codehaus/janino/ScriptEvaluator;
[error] at com.oracle.svm.core.util.VMError.shouldNotReachHere(VMError.java:70)
[error] at com.oracle.svm.hosted.NativeImageGenerator.doRun(NativeImageGenerator.java:636)

This is with the flags "--no-fallback", "--allow-incomplete-classpath", "--verbose"

It should be possible to make this native image without org.codehaus.janino.ScriptEvaluator being on the class path if --allow-incomplete-classpath command line option is used as in this case. The method name appearing in the stack trace of shouldNotReachHere makes me believe this is not an intentional failure scenario.

I confirm this issue, have you the information if it was introduced on 19.3.0 ?

I've tested on 19.3.0

[NAJ10]

Yes it seems to have been introduced with 19.3.0. I could not reproduce the problem with graalvm-ce-linux-amd64-19.2.1.tar.gz as the image builds and runs successfully. I also tried graalvm-ce-java8-linux-amd64-19.3.0.tar.gz and it also shows the same VMError$HostedError: java.lang.NoClassDefFoundError as the java-11 variant of 19.3.0

confirmed - moving back to 19.2.1 eliminates the problem.

As a work around, adding a dependency on Janino fixed this issue for me. I.e. adding the following sbt configuration:

libraryDependencies +=  "org.codehaus.janino" % "janino" % "3.1.0"

Try adding --initialize-at-build-time=ch.qos.logback.core.boolex.JaninoEventEvaluatorBase if JaninoEventEvaluatorBase is on your classpath.

--allow-incomplete-classpath should now report the missing class at run time, if the code path is actually executed.
