The following tier1 test failed in a jdk/jdk CI job set:

gc/parallel/TestPrintGCDetailsVerbose.java

Here's a snippet from the hs_err_pid file:

# Internal Error (t:/workspace/open/src/hotspot/share/classfile/javaClasses.cpp:1479), pid=3196, tid=16372
# assert(oopDesc::equals(Universe::java_mirror(type), java_class)) failed: must be consistent

And here's the crashing thread's stack trace:

This is a tier1 failure so the priority starts out at P2.
I can't find any older sightings in a CI build so I'm
tagging this as a promotion_blocker.
