[9] Review request for 8160623: [PIT] Exception running java/awt/event/KeyEvent/KeyChar/KeyCharTest.java

[Semyon Sadetsky]

Hello,

Please review fix for JDK9:
bug: https://bugs.openjdk.java.net/browse/JDK-8160623

webrev: http://cr.openjdk.java.net/~ssadetsky/8160623/webrev.00/

This a regression from JDK-8139189. The wchar array may contain all 
zeroes for some known keys (likely for Delete key only) and it should 
not be interpreted as  CHAR_UNDEFINED.
