RFR: 8212676 AIX's CDE/MWM support

[Ichiroh Takiguchi]

Hello.

Could you review the fix ?

Bug:    https://bugs.openjdk.java.net/browse/JDK-8212676
Change: https://cr.openjdk.java.net/~itakiguchi/8212676/webrev.00/

Test instructions and screen shots are in JDK-8212676.

GUI environment for AIX platform still needs CDE support.
This fix is required to avoid unexpected working behavior on AIX 
platform.

I'd like to obtain a sponsor for this issue.

Thanks,
Ichiroh Takiguchi
