Launch4J generating invalid JARs

[Joshua Turner]

I have a set of five applications which use a common launch4j configuration. Four of them generate working executables. One does not. The one that does not also fails to parse as a ZIP file using the built-in Java zip libs, nor does it parse with the MS Windows zip libs.

Execution yields:

Error: Could not find or load main class the.real.fully.qualified.package.App

(With the real name of the application masked for client confidentiality reasons.)

The resultant file does have the full byte stream of the JAR from which it was made starting at offset 0xb800.

Output of --l4j-debug-all follows:

Just to make sure, were you able to parse the jar before wrapping it with launch4J? As a temporary solution you can create a launcher without wrapping the jar.

I've confirmed that the JAR parses fine without launch4j. I'll try the temp solution and see if it meets requirements at this end.
