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
