How do I solve a missing reference issue? (since 2022-09) [message #1857163]

I have a setup under macOS where I have three different JDK versions: Eclipse Temurin 8 [1.8.0_312], Eclipse Temurin 11 [11.0.3], and Eclipse Temurin 17 [17.0.1]. I have a workspace with a project that must rigorously be built with Java 8 (it is a JVM written in Java that only supports Java 8 and metacircularly exploits the libraries of the environment it runs on). The project is built with Gradle. If you need to have a look at it you can find it at https://github.com/pietrobraione/jbse. Until Eclipse 2022-09 I had no problem importing the project under Eclipse, but since Eclipse 2022-09 I have the following compilation problem:

The type java.lang.invoke.VarHandle cannot be resolved. It is indirectly referenced from required .class files

where the class java.lang.invoke.VarHandle is not used by the resource generating the compilation problem. Note that java.lang.invoke.VarHandle is introduced since Java 9. Building everything with Gradle (by double-clicking the build task in the Gradle Tasks view) works well, so the issue is Eclipse compiling the project with ECJ. The only workaround I was able to find is to copy the class generated by the Gradle compilation in the bin/ folder of the project and replace the one generated by the Eclipse ECJ compilation. Is there any better option?

Thank you
Pietro
