20033	MacOS app doesn't launch on first run	Stereo	Stereo	"When opening a quarantined app for the first time, macOS 10.15 and earlier passes an extra -psn_0_XXX argument, where XXX is the process serial number. This is a legacy behaviour from the days of the Carbon framework and collaborative multitasking.

This means that with the new builds, JOSM.app will close on its first run, and run fine on every subsequent run.

This has been reported as a java bug (https://bugs.openjdk.java.net/browse/JDK-8240877). In the meanwhile, you might have to open JOSM twice after installing it.

A workaround could be to ignore the -p argument.

The problem doesn't happen in macOS Big Sur (11.0.1)."	defect	closed	normal		Installer MacOS	latest	othersoftware	macos javabug othersoftware
