Hi,

Please find below a patch for a test bug:
8031068: java/util/logging/ParentLoggersTest.java:
         checkLoggers: getLoggerNames() returned unexpected loggers

https://bugs.openjdk.java.net/browse/JDK-8031068


<http://cr.openjdk.java.net/~dfuchs/webrev_8031068-jdk9/webrev.00/>

As usual - the issue is that the test creates loggers without
keeping any strong reference - thus allowing for the possibility
that they will be garbage collected too soon.

I managed to reproduce systematically by adding a call to
System.gc() between the creation of the two loggers - and
passing -Xcomp -server to the VM.
With the fix the test no longer fails in that configuration.

best regards,

-- daniel
