Review request: test/java/util/logging/ParentLoggersTest.java fails in samevm mode

[Mandy Chung]

Fixed 6961408: test/java/util/logging/ParentLoggersTest.java fails in 
samevm mode

Webrev at:
   http://cr.openjdk.java.net/~mchung/6961408/webrev.00/

This fix updates the test to check the list of loggers before and after 
the test run and also takes out all logging tests from the ProblemList.txt.

Thanks
Mandy
