<Swing Dev> [12] Review Request: 8199072 Test javax/swing/GroupLayout/6613904/bug6613904.java is unstable

[Sergey Bylokhov]

Hello.
Please review the fix for jdk 12.

Bug: https://bugs.openjdk.java.net/browse/JDK-8199072
Webrev: http://cr.openjdk.java.net/~serb/8199072/webrev.00

Bug was found when our tests executed in the "agentvm" mode.
The reason of test failure was the jtreg not able to interrupt EDT,
on which the test was executing.

The root cause is that the test uses "invokeLater()", which do
not wait when the runnable will be completed. And since jtreg will
assumes that completion of the main() is the end of the test it will
try to stop EDT.

I have verified that if the fix for JDK-8199022(which
added "javax/swing" to the "othervm.dirs" in the TEST.ROOT) is reverted,
the test will start to fail again.

Even if the test currently always passes, we have an opposite issue,
the jtreg may report "PASS" status for the test even before the "Runnable"
will start to execute.

As a fix invokeLater() is replaced by the invokeAndWait().
