Illegal reflective access in ContextOverridingClassLoader.isEligibleForOverriding

[geiliev]

Affects: 6.0.11

---

Related to #22791
The fix in the related issue doesn't resolve the problem and the application still fails to start.
The problem is that event though the findLoadedClass method is inaccessible it is still called in isEligibleForOverriding which results in an IllegalAccessException and failure to start the application.

Can you share a minimal sample application that reproduces the problem? Thanks!

Oops, looks like there is a method = null; missing there in the catch block in case of makeAccessible failing. This just missed the 6.0.12 release by a day, so we'll fix it for 6.0.13 where this will be available in snapshot builds soon.

For the time being, and actually as a general recommendation since it increases the performance of temporary class loading, please set --add-opens=java.base/java.lang=ALL-UNNAMED on the command line.

Thank you, I have added --add-opens=java.base/java.lang=ALL-UNNAMED anyway and it is working.
Just thought it will be nice to work without it as well.
