Updated the webrev
- renamed variable to "test"
- removed reset to null
- removed extra parens in exception message
- updated @bug tag
I have never seen the failure with PlatformLoggingMXBeanTest,
and I had previously done a gc right after the Logger assignment.
Seems to be a reasonable update to use the instance variables
in case the previous failures were caused by the logger being gc'ed.
