[Pljava-dev] VM initialization failure

I've gone for the blackdown 1.4.2-rc1 (AMD64) version and it has got me
to a new place - perhaps a step back!

When I try:

SELECT sqlj.install_jar('file://opt/pgsql/lib/sqlj.jar','sqlj','true');

my /var/log/pgsql.log is showing:

Error occurred during initialization of VM

I've recompiled pljava and reinstalled it (with the -reinstall switch).
I've restarted the pgsql instance

I originally removed the LD_LIBRARY_PATH but this took me back to the
system not finding libjvm.so so I added it back in.

I'm on Postgres 8x

My postgresql.conf custom_variable_classes and pljava.classpath are set:

custom_variable_classes = 'pljava'
pljava.classpath = '/opt/pgsql/pljava/build/pljava.jar'

I've checked permissions on the postgres user and from su - postgres I
can see pljava.jar and I've opened it in file roller the it appears to
be intact.

Any other ideas ?
