The `META-INF/versions/x` class files are compiled to the wrong version of Java

Open jamezp opened this issue 1 year ago • 2 comments

The META-INF/versions are used for Multi-Release JAR's. It looks this project produces an MR JAR for 9 and 21. However, in both cases the class has a bytecode level of Java 1.8, which doesn't seem right.

META-INF/versions/21/reactor/core/scheduler/BoundedElasticSchedulerSupplier.class:                                           compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/21/reactor/core/scheduler/BoundedElasticThreadPerTaskScheduler$BoundedServices$1.class:                    compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/21/reactor/core/scheduler/BoundedElasticThreadPerTaskScheduler$BoundedServices$ActiveExecutorsState.class: compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/21/reactor/core/scheduler/BoundedElasticThreadPerTaskScheduler$BoundedServices.class:                      compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/21/reactor/core/scheduler/BoundedElasticThreadPerTaskScheduler$SchedulerTask.class:                        compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/21/reactor/core/scheduler/BoundedElasticThreadPerTaskScheduler$SequentialThreadPerTaskExecutor.class:      compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/21/reactor/core/scheduler/BoundedElasticThreadPerTaskScheduler$SingleThreadExecutorWorker.class:           compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/21/reactor/core/scheduler/BoundedElasticThreadPerTaskScheduler.class:                                      compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/21/reactor/core/scheduler/VirtualThreadFactory.class:                                                      compiled Java class data, version 52.0 (Java 1.8)
META-INF/versions/9/reactor/core/publisher/CallSiteSupplierFactory.class:                                                    compiled Java class data, version 52.0 (Java 1.8)

As you can see the byte code version is 52 which is Java 1.8. This is causing an issue with the maven-site-plugin.

Expected Behavior

The byte code version should match the version being targeted.

Actual Behavior

The byte code version is 52.0.

Steps to Reproduce

Compile project and check the files generated in the META-INF/versions directory. What I did was run:

file META-INF/versions -name "*.class" | xargs -I {} file "{}"

Your Environment

Currently using reactor-core 3.6.6, but downloaded 3.6.7 and noticed the same issue.

  • Reactor version(s) used: Currently 3.6.6, but downloaded 3.6.7 to verify
  • Other relevant libraries versions (eg. netty, ...): N/A
  • JVM version (java -version): Java 21
  • OS and version (eg uname -a): Linux 6.9.4-200.fc40.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Jun 12 13:33:34 UTC 2024 x86_64 GNU/Linux

Thank you for the report. Indeed, something is wrong. I don't know yet what is wrong in our configuration. We use a combination of mrjar-gradle-plugin with Gradle toolchains. If you have any clue whether we are doing something wrong, feel free to comment here or open a PR. I will be away for a week, but once I'm back I'll investigate if there are no ideas in the meantime.

No worries. For my specific case I was able to easily workaround it. I'm not too familiar with Gradle TBH, but if I find some time I can have a look.
