There is a policy:

https://fedoraproject.org/wiki/Packaging/Java#Packaging_JAR_files_that_use_JNI

but some existing packages may not follow it.

Ideally jss and tanukiwrapper would be updated to follow the packaging
guidelines.

What is the symptom of this problem?

I'm not sure what you mean by this.
