java/awt/MouseAdapter/MouseAdapterUnitTest/MouseAdapterUnitTest.java failed on linux with jdk6

test java/awt/MouseAdapter/MouseAdapterUnitTest/MouseAdapterUnitTest.java failed on linux since jdk6 fcs

test consistently failed with jdk6u51b04 and intermittently failed with jdk6b105, jdk6u45b05; I can't reproduce the same failure with jdk7; it failed with jdk7 as JDK-6849369 sometimes
test passed on windows 7 64 bit with jdk6u51b04

It can be timing issue
