Just to add to Daniel's comment. JAR indexing has several issues, most going back 20+ years. We toyed with the idea of removing it in JDK 18 but decided to keep it disabled for now with a view to removing the code in a future release. It's not clear to me that it's worth trying to fix issues but maybe the motive is to back-port a fix to an older release? (I can't quite tell if you have something that runs into the issue or whether you just spotted the open issue).
