RFR: 8258061: Improve diagnostic information about errors during class redefinition [v3]

[Leonid Mesnik]

> 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.
