ADDITIONAL SYSTEM INFORMATION :
macOS 10.15.7, java 15 and 16-ea

A DESCRIPTION OF THE PROBLEM :
MacOS adds a ProcessSerialNumber to args when launching a quarantined app for the first time, like "-psn_0_10615327"

The jpackage wrapper should filter out the psn since it's not expected in the app

 https://trac.wxwidgets.org/ticket/15432

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Download a .app produced by jpackage. Open it for the first time.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No argument get passed to the app except the ones specified by --arguments in the jpackage call. The jpackage wrapper catches and filters the -psn_x_yyy arguments passed by the OS.
ACTUAL -
Spurious "-psn_x_yyy" argument gets passed

---------- BEGIN SOURCE ----------
The process to package and sign a macOS app is a bit complex, but I've produced a build at https://stereo.dev.openstreetmap.org/JOSM.zip . It will crash on the first run because it gets an argument it didn't expect, and log the error at /tmp/josm-err.txt. Arguments will be logged at /tmp/josm-out.txt
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
MacOS only seems to pass that psn argument to quarantined apps when they're being run for the first time. Opening the .app for a second time, or manually clear the quarantine flags, is a workaround.

It is also possible to ignore -psn_x_yyyy arguments in your java program.

FREQUENCY : always
