RFR: 8258061: Improve diagnostic information about errors during class redefinition

Thu Dec 17 00:49:02 UTC 2020

The error code during class redefinition might be not enough to easily diagnose the problem. Some more logging might be useful to understand it. I encountered this problem when redefined methods with lambda usage.
I run all existing tests with enabled logging and sanity verified error messages.
