[macosx] Error when using setDesktopManager on a JDesktopPane on MacOS X with Look and Feel Aqua

FULL PRODUCT VERSION :
java version "1.8.0_112"
Java(TM) SE Runtime Environment (build 1.8.0_112-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b16, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Mac OS X :
Darwin Kernel Version 16.1.0: Thu Oct 13 21:26:57 PDT 2016; root:xnu-3789.21.3~60/RELEASE_X86_64 x86_64

A DESCRIPTION OF THE PROBLEM :
When using
desktop.setDesktopManager(new DefaultDesktopManager());
with LookAndFeel com.apple.laf.AquaLookAndFeel,
iconifying JInternalFrames causes crash.

REGRESSION. Last worked in version 6u45

ADDITIONAL REGRESSION INFORMATION:
Don'l know if regression occurred with Java 7

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Taking the InternalFrameDemo source code :
https://docs.oracle.com/javase/tutorial/uiswing/examples/components/InternalFrameDemoProject/src/components/InternalFrameDemo.java

If you add
desktop.setDesktopManager(new DefaultDesktopManager());
in the Constructor,
next time you'll try to iconify an internalframe, the problem will occur.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No crash expected
