[macosx] sigsegv (0Xb) Being Generated When Starting JDev With Voiceover Running

Technical Environment (Product Version, JDK Version, Patches Applied, etc.):
----------------------------------------------------------------------------
Mac OSX 10.8 mountainLion
jdk 1.7.0_21, 1.7.0_51 (tried the older jdk to see if it was a problem with
the newer jdk build).
JDeveloper 12.1.2.0.0

Problem Description:
--------------------
This problem was reported by a customer.

After installing JDeveloper the customer tried to launch JDeveloper from the
JDeveloper.app app file, and while it starts to launch, eventually it just
hangs.

He then tried running $JDEV_HOME/jdeveloper/jdev/bin/jdev from a terminal
window and was able to determine that a segmentation fault was being
generated (see log file).

The user was running the VoiceOver screenreader on his Mac.

Per a suggestion he tried starting JDeveloper with VoiceOver turned off, and
with sighted assistance. JDeveloper started fine. He then restarted
VoiceOver and it was able to read JDeveloper's controls fine.

This is what I see when I start jdeveloper (12.1.2 or 12.1.3) with the Voice
Over enabled:
