JNLP property apple.laf.useScreenMenuBar no longer treated as secure for Mac OS

FULL PRODUCT VERSION :
Java Web Start 11.40.2.25
Using JRE version 1.8.0_40-b25 Java HotSpot(TM) 64-Bit Server VM

ADDITIONAL OS VERSION INFORMATION :
Mac OS X 10.9.3 (13D65)

EXTRA RELEVANT SYSTEM CONFIGURATION :
Mac Mini Late 2012
Firefox 36.0.1.

A DESCRIPTION OF THE PROBLEM :
Java application launched by unsigned dynamically-generated JNLP will run, but missing user interface features like menus, dialog boxes and response to function keys.

Missing features render application unusable to Mac OS X users.

Normally menus are enabled by setting apple.laf.useScreenMenuBar to true in resources section of JNLP.

As early as September 2010, this property was secure for Mac OS X but insecure for other OS.

This leads me to believe there used to be a special build of Java for Mac OS X, and this issue may be a side-effect of an initiative to unify the codebase.

Maybe incomplete documentation led to oversight because no Apple properties are listed among "The following properties, as well as properties beginning..."

POSSIBLE DUPLICATE: JDK-8075070
NOT DUPLICATE: JDK-8024720 (Has workaround, place property near top of resources section)


REGRESSION. Last worked in version 8u31

ADDITIONAL REGRESSION INFORMATION:
Java Web Start 11.31.2.13
Using JRE version 1.8.0_31-b13 Java HotSpot(TM) 64-Bit Server VM


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Launch application that needs menus with unsigned JNLP containing resource property apple.laf.useScreenMenuBar

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Application launches and menu interface appears
ACTUAL -
