Hmm, I just found this in https://fedoraproject.org/wiki/Packaging:Java?rd=Packaging/Java#Packaging_JAR_files_that_use_JNI "JAR files using JNI or containing JNI shared objects themselves MUST be placed in %{_jnidir} and CAN BE symlinked to %{_libdir}/%{name}." So, it seems as though the practice of putting DSOs into jarfiles is legitimate. I am appalled that this suggestion got past Fedora packaging, but I can't deny that it's there. The only sensible thing to do, if we must put DSOs into jarfiles, is to generate the DSO with proper debuginfo.
