Description

Groovy uses ASM 9.6, which support up to Java 22. Using ASM 9.7 would allow to support Java 23. I have the following Stack Trace:

BUG! exception in phase 'semantic analysis' in source unit 'Script_83d220891ea7c7d06c78121cd044992a.groovy' Unsupported class file major version 67
               at org.codehaus.groovy.control.CompilationUnit$ISourceUnitOperation.doPhaseOperation(CompilationUnit.java:901)

               at groovy.lang.GroovyClassLoader.doParseClass(GroovyClassLoader.java:373)
 

I uses Groovy 4.0.16 but looking on the logs for versions it appears that the ASM version has not be upgraed since this version.
