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
