Hello,
please review a fix for JDK9:
webrev: http://cr.openjdk.java.net/~ssadetsky/7172652/webrev.00/
bug: https://bugs.openjdk.java.net/browse/JDK-7172652
***ROOT CAUSE
This is a bug in Label UI's key release event processing routine for key
mnemonics: only one release event is captured instead of two (Alt
release and the mnemonic key release). The Alt release event goes up on
hierarchy and is captured by the parent internal frame's menu bar for
which Alt key release means selection change event under the Windows
system LnF.
***SOLUTION
Change key release event handling logic to capture events from both Alt
modifier and the key. The logic takes into account that when the first
release key event come it transfers focus back to the field so the
second key release event should be captured from any window component.
***TESTING
A simple scenario is written to exclusively cover the situation.
