Hello,
    could you please review the following fix:

<http://cr.openjdk.java.net/%7Eanashaty/8073008/9/webrev.00/>
bug: https://bugs.openjdk.java.net/browse/JDK-8073008

    Problem: any IM with a lookup window on Mac works incorrectly: when 
selecting a variant with arrows keys or confirming with Enter key all 
key events are also passed to the underlying text document which leads 
to cursor walking and other unwanted artifacts.

    Fix: while native IM is active key events shouldn't be passed to Java

Thanks!
Anton.
