ADDITIONAL SYSTEM INFORMATION :


A DESCRIPTION OF THE PROBLEM :
Assertion due to Type.addMetadata adding annotations to already-annotated type. Javac appears to try to annotate a type twice during certain erroneous compilations. It should produce a compile error report, but throws instead.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
You will need:

https://github.com/CCBlueX/LiquidBounce commit 5170bccb9416c667ad8f399b8f624d525d93826d

Jars:
Jetbrains annotations 20.1.0 from https://mvnrepository.com/artifact/org.jetbrains/annotations/20.1.0
Kotlin compiler emeddable 1.9.0 from https://mvnrepository.com/artifact/org.jetbrains.kotlin/kotlin-compiler-embeddable/1.9.0

Now run:

/tmp/jdk-22.jdk/Contents/Home/bin/javac src/main/java/net/ccbluex/liquidbounce/injection/mixins/minecraft/gui/MixinChatInputSuggestor.java -cp /tmp/jars/annotations-20.1.0.jar:/tmp/jars/kotlin-compiler-embeddable-1.9.0.jar

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Compilation errors, since many jars and other source files are missing from the compile command.
ACTUAL -
Note: Annotation processing is enabled because one or more processors were found
  on the class path. A future release of javac may disable annotation processing
  unless at least one processor is specified by name (-processor), or a search
  path is specified (--processor-path, --processor-module-path), or annotation
  processing is enabled explicitly (-proc:only, -proc:full).
  Use -Xlint:-options to suppress this message.
  Use -proc:none to disable annotation processing.
An exception has occurred in the compiler (22). Please file a bug against the Java compiler via the Java bug reporting page (https://bugreport.java.com) after checking the Bug Database (https://bugs.java.com) for duplicates. Include your program, the following diagnostic, and the parameters passed to the Java compiler in your report. Thank you.
