What is the motivation / use case for changing the behavior?

want to package the jar inside the executable to hide the jar file from the user

Hi @akhilmanikandan!

I've been doing some tests with DEB package generation, trying with linuxConfig.wrapJar=true and false, and in both cases it worked like a charm.

So, do you mean that it fails when setting linuxConfig.wrapJar=true and only when is installed from DEB package? Have you tried to run your app directly from the generated app folder in target.

The only thing I've not tried yet is using a customized fat jar. Maybe this could be the problem.

[fvarrui]

I've just tested it using a fat jar without problems. If you are bundling all your dependencies in a fat jar, you should set copyDependencies=false.

[akhilmanikandan]

the problem seems to be size, if the fat jar is small it works, looks like exisiting issues with big jars in launch4j

But your problem wasn't in Ubuntu?

Anyway, JP supports other kind of EXE files for Windows

[akhilmanikandan]

issue is across ubuntu and windows , its the same issue, something to do with packaging, it works if i create a small fat jar and class not found when i create a fat jar above 120mb
