1 Answer:
Please try with lower versions of Apache Derby DB JDK
Faced similar issue with jasper reports server 7.8.0 community edition, Derby 10.15, compatible with JDK 9+ was not loading.

Workaround: Use Derby 10.14, compatible with JDK 8+, and Derby DB loads.

Error seen in logs: jar file has been built with version 53 and higher, can read only version 52 and lower
Its happening for me as well. Any suggestions here.
