[Pljava-dev] [Fwd: Unable to load class org/postgresql/plsql/internal/Backend]

Hi - I've gone with Blackdown now and I'm getting a VM initialization
error - which I've moved in to a new thread.

I've replicated your dynamic_library_path and LD_LIBRARY_PATH (note I
still don't have pljava in /usr/lib64 - but in /opt/pgsql/lib so that's
the only difference.
