Can you please apply the below patch and tell me if it solves your
problem?  Proper procedure should be:

# cd /usr/ports/java/diablo-jre16
# patch < /wherever/the/patch/is
# make clean
# make
# make deinstall
# make install

After this is done, use "ldconfig -r" and look at the search path
shown at the top; hopefully /usr/local/diablo-jre1.6.0/lib/amd64
will be there, and libjava.so should be found (hopefully).

Set the LD_LIBRARY_PATH environment variable to the search paths
you desire.  Colon-delimited, and it overrides the defaults.  E.g.

export LD_LIBRARY_PATH="/lib:/usr/lib:/usr/lib/compat:/usr/local/lib:/usr/local/diablo-jre1.6.0/lib/amd64"

But the below patch, assuming it works (and I got the paths right),
should not require you to do that.  LD_LIBRARY_PATH is somewhat evil,
and it's not recommended you use it.
