FULL PRODUCT VERSION :

A DESCRIPTION OF THE PROBLEM :
the launcher generated from "javapackager -deploy ..." (that use libpackager.dylib) behaves differently from the application launched by java command line.
in particular the use of system property 'apple.laf.useScreenMenuBar' doe not work at all when launched from the javapackegr launcher (opening the .app that contains libpackager.dylib, Info.plist and the binary executable with the app name) insted works well when launched from terminal with java command line (java -jar App.jar)




STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Create a JFrame and launch with apple.laf.useScreenMenuBar = true, no menu bar at top of the screen

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
as prior macOs version we expect appearing the java app menu on macOs top screen menu
ACTUAL -
no menu bar at all

ERROR MESSAGES/STACK TRACES THAT OCCUR :
no error logged

REPRODUCIBILITY :
This bug can be reproduced always.
