This is why jpackage tries to sign added files and this is expected behavior by jpackage. "codesign" fails since added content made application bundle structure invalid. There is nothing we can do on jpackage side to sign such invalid bundles. As proposed solution we will output possible reason for "codesign" failure if it fails and `--app-content` was specified and possible solution. Proposed message: "One of the possible reason for "codesign" failure is additional content provided via "--app-content", which made application bundle structure invalid. Make sure to provide additional content in a way it will not break application bundle structure, otherwise add additional content as post-processing step."

Probably the additional content broke the integrity of the application bundle and caused the failure. Ensure content supplied via the "--app-content" parameter does not break the integrity of the application bundle, or add it in the post-processing step.
