FULL PRODUCT VERSION :
java version "1.8.0_51"
Java(TM) SE Runtime Environment (build 1.8.0_51-b16)
Java HotSpot(TM) Client VM (build 25.51-b03, mixed mode, sharing)



ADDITIONAL OS VERSION INFORMATION :
Windows 7, version 6.1

A DESCRIPTION OF THE PROBLEM :
The test ''java/awt/event/InputEvent/EventWhenTest/EventWhenTest.java'' fails with the message "No events were received"

The issue is intermittent, it fails in ~3 of 20 runs. Sometimes the test fails because of time out.
It was observed on Linux and Windows.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
The test is located at http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/file/774f11d707e0/test/java/awt/event/InputEvent/EventWhenTest/EventWhenTest.java
It is difficult to reproduce - I was not able to reproduce it as standalone test. It was reproduced running in a group java/awt/event
