Ignore Classes That Are Too New

Ignore Classes That Are Too New

gudenau opened this issue 4 years ago · 1 comments

When trying to run with Mixins on Java 17 (don't ask) it freaks out and causes several base classes to fail to load because the class version is too new.

It would be best to ignore this, especially since they are part of the STD lib and not touch them. In this case it would allow for Mixin to continue to work with new JVM versions even if it is discontinued in the future.

Example log output:

This has already been fixed, loader 0.11.2 contains the fix.
