Lukasz Lenart resolved WW-5207.
-------------------------------
Resolution: Fixed
{{Opcodes.ASM9}} is used by default
> Convention Plugin - support for ASM 9
> -------------------------------------
>
> Key: WW-5207
> URL: https://issues.apache.org/jira/browse/WW-5207
> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - Convention
> Affects Versions: 6.0.0
> Reporter: Mirek Hankus
> Priority: Major
> Fix For: 6.0.1
>
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> According to https://issues.apache.org/jira/browse/WW-5148 support for ASM
> 9.2 was implemented which implied support for JAVA 17. Unfortunately, this
> is not true, because convention plugin fails to start when app is compiled
> with JAVA17
> This issue is very similar to https://issues.apache.org/jira/browse/WW-5005
> which concerned JAVA 11.
> Convention plugin contains code
> {code:java}
> public class InfoBuildingVisitor extends ClassVisitor {
> private Info info;
> private ClassFinder classFinder;
> public InfoBuildingVisitor(ClassFinder classFinder) {
> super(Opcodes.ASM7);
> this.classFinder = classFinder;
> }{code}
> which limits usage only to ASM7
> Right now following exception it thrown if you try to run struts 6.0 app
> compiled with java 17
> {code:java}
> java.lang.UnsupportedOperationException: PermittedSubclasses requires ASM9
