Fix 1. of https://issues.apache.org/bugzilla/show_bug.cgi?id=48831#c3
Ignore the reset() call from java.util.logging.LogManager.Cleaner,
because we have our own shutdown hook that will take care.

There are three hooks that run at VM shutdown:
1. j.u.l.LogManager.Cleaner
2. o.a.j.ClassLoaderLogManager.Cleaner
3. o.a.c.startup.Catalina.CatalinaShutdownHook
2. vs. 3. was taken care by r910974 and r918594. This takes care of 1. vs. (2.,3.)
