Hi there. I have another case where running jpackage emits
Bundler DEB Bundle failed because of java.lang.NullPointerException: Cannot invoke "java.lang.CharSequence.length()" because "this.text" is null I have never experienced NullPointerExceptions in other JDK tools. Seems to me JPackage is a new kid on the block. In this case, JPackage is invoked to finish from an existing appimage to the final package. the failure is caused because some important files are missing in appimage. The previous run is even more puzzling for me. It is supposed to create the appimage directory. And while it emits no error message, on my development machine it runs reliably while on the Github Runner it just does not create all files - no error message, no exit code - nothing. Any idea what I could be looking at? Hiran On Mon, 2022-04-04 at 08:49 +0200, Hiran Chaudhuri wrote: > Hello Alex, > > I tried running the same command with the jdk19 you pointed at.
