[8u] review request: 8139326: [TEST] Unit tests for JFXPanel with security manager don't detect errors

[Kevin Rushforth]

Hi Chien,

Can you do a quick sanity test review of the backport to 8u-dev of the 
following:

https://bugs.openjdk.java.net/browse/JDK-8139326
http://cr.openjdk.java.net/~kcr/8139326/webrev.00/

This was earlier reviewed (by you) for 9-dev with the intent to backport 
to 8u-dev, but the backport wasn't completed at that time. Since enough 
time has past, I would like a sanity check before pushing to 8u-dev. The 
patch that was pushed to 9-dev imports cleanly into 8u-dev and works as 
expected.
