Description
I have some .jar files that I want to open. It can't open, and when I right click it, and go to open with, the default is "JavaLauncher", instead of the usual "Jar launcher". I'm pretty sure my mac doesn't have "Jar launcher".

Research direction
Start by reproducing the reported behavior on macOS with a .jar file and compare the Open With entries showing JavaLauncher instead of Jar launcher. Trace the installer behavior related to macOS file associations; done means the installed Java application opens .jar files through the expected launcher.
