Gary Gregory commented on LOG4J2-1127:
--------------------------------------
Your first stack trace shows that a {{weblogic.application.ModuleException}}
was caught and logged. The cause of the caught
{{weblogic.application.ModuleException}} is an
{{UnsupportedOperationException}}.
So I do not see how your pull request could catch a
{{UnsupportedOperationException}} since that is not what is at the top of your
stack trace.
OTOH, by catching an {{Exception}} we catch all subclasses, and then look for
the {{UnsupportedOperationException}}.
But now, looking at your second stack trace, it is not a
{{weblogic.application.ModuleException}} that is caught at the top, it is an
{{Exception}}. Absolutely horrible coding, the king of anti-patterns.
I'll adjust again, stay tuned.
