I don't have any mac nor I know what homebrew does, neither who created this stuff. I cannot analyze the issue and have no idea if we should do something. Can you please investigate? Only a macOS user can solve this kind of stuff.

It's mentioned as a method of installation at https://josm.openstreetmap.de/wiki/Download#brew.
https://github.com/Homebrew/homebrew-cask-versions/blob/master/Casks/josm-latest.rb looks to be the install script that is run.
Could it be related to us both only having JDK11. After installing JDK8 it works just fine of course!
I'll open a pull request to update the cask to include a caveat that JSOM.app requires JDK8 to be installed.
The install instructions could also be updated to include...
$ brew tap homebrew/cask-versions $ brew cask install java8

See https://github.com/Homebrew/homebrew-cask/pull/58808, which should help highlight this dependency once merged.

Ah, maybe this is unrelated to brew but we need to update the library that generates the .app file. JOSM is compatible with Java 11, this is only a packaging issue.

Can you please try to uninstall Java 8 and launch https://josm.openstreetmap.de/raw-attachment/ticket/17278/josm-custom-macosx.zip ? I have used https://mvnrepository.com/artifact/com.panayotis/appbundler/1.1.0 hoping it works with Java 11.

Seems okay.
Uninstalled Java 11, and installed Java 8 again with brew.
brew cask zap java brew cask install java8
I'm also getting the same issue.
macOS 10.14.2
java openjdk 11.0.2
Have installed JOSM today using brew. Tried opening JOSM which reported the java error, so have installed java using brew too, but still get the error.
