Hi Abdul, Did you observe this issue on OS X with JDK 9 ?
03-11-2016
Reproduced with java/awt group test in windows environment - attached the error log. 8u51 b09 - 88u51_MouseClickTest_error_log.txt 8u122 b04 - 8u122_MouseClickTest_error_log.txt JDK9 build 142 - JDK9_build142_MouseClickTest_erro_log.txt

According to the submitter, unfortunately, I have no chance to run these tests against JDK 9ea yet.

According to the bug submitter, If you are interested in failures of this test then as stand-alone test case you can use the test located at http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/b30ecba1cd23/test/java/awt. The failures of this test I reported was observed running the test via jtreg. Please note in some cases it is difficult to reproduce running as a stand-alone test, it is also difficult to reproduce it via jtreg running only one test - so you probably need to run a group of tests like java/awt or java/awt/Focus.

Requested bug filer to confirm us whether the issue is reproducible with JDK 9ea or not.
