test closed/java/awt/Focus/KeyStrokeTest/KeyStrokeTest.html fails sometimes

reproduced on windows 7 64 bit

the button doesn't disappear and text field doesn't receive key typed event

I can't reproduce issue with jdk7u21b14 on the same platform and with jdk8 on the linux platform but may be need to run test more times

failure output:
