> During the testing of [JDK-8348752](https://bugs.openjdk.org/browse/JDK-8348752), we notice test failures caused by unverifiable old classes (i.e., classes with bad instructions and major version < 50).
> 
> The fix is simple. Simply exclude unlinked classes from the AOTCache when `-XX:+AOTClassLinking` is enabled.
> 
> Verified with JCK.

Ioi Lam has updated the pull request incrementally with one additional commit since the last revision:

  Exclude test cases that assume (verifiable) old classes are always archived; but they are now not archived when -XX:+AOTClassLinking is enabled
