We used AspectJ 1.9.19, which was running perfectly. Now, we wanted to update to 1.9.21 for JDK 21 compatibility, but unfortunately, this leads to an exception:

when batch building BuildConfig[null] #Files=0 AopXmls=#0
RELEASE_17
java.lang.NoSuchFieldError: RELEASE_17

The problem occured here: https://github.com/kieker-monitoring/kieker/actions/runs/7421484999/job/20194928410 I am locally running Ubuntu 22.04 with OpenJDK 11, but I assume that this happens on JDK 11 regardless of the OS.

The problem occurs when just cloning (git clone https://github.com/kieker-monitoring/kieker.git), and then running ./gradlew compileJava. Since we internally do not use this field, I assume that this has something to do with either the AspectJ compiler itself or the aspectj Gradle plugin (https://plugins.gradle.org/plugin/io.freefair.aspectj - we use the newest version 8.4).

It seems like the file where this occurs is https://github.com/eclipse-jdt/eclipse.jdt.core/blob/33ad538b4d523b0fbc99b99d17222e846ec1893a/org.eclipse.jdt.core.compiler.batch/src/org/eclipse/jdt/internal/compiler/apt/dispatch/BaseProcessingEnvImpl.java#L49 The SourceVersion.RELEASE_17 is not available in Java 11, so this fails. 

As far as I see it, the JDT Core would need to downgrade this to RELEASE_11, or AspectJ needs to state that 1.9.21 is only runnable with Java 17+. According to https://github.com/eclipse-aspectj/aspectj/blob/master/docs/dist/doc/JavaVersionCompatibility.md, AspectJ should also work with Java 8+, which seems not to be true.

Is there any solution / workaround for this problem?
