Build on master fails for Java 11 builds due RocksDB JNI Issues

jtstorck recently got the Java 11 build for NiFi working and it was merged.

devriesb recently got the RocksDB flowfile impl commited. However, it doesn't appear to work on Java 11 builds.

This needs to be resolved as we need Java 11 builds to work going forward.

Can you two please coordinate and resolve.
