<AWT Dev> <AWT-Dev> [8] Review Request: JDK-8011142 [TEST_BUG] 2 AppContext regression tests failed since 7u25b03 with NullPointerException

[Petr Pchelko]

Hello, AWT Team.

Please review the fix for the issue:
https://bugs.openjdk.java.net/browse/JDK-8011142
The fix is available at:
http://cr.openjdk.java.net/~pchelko/8011142/webrev/

The MainAppContext test verified that the mainAppContext is created when there's already another AppContext created. 
After the AppContext fix this is incorrect, so the test should be removed, as it's expecting the wrong behavior. The second
test mentioned in the bug was already fixed.

We cannot modify the test, because it's testing exclusively the behavior which is wrong now.

Thank you.
With best regards. Petr.
