Yes, besides my system has currently only one jdk installed,
i made pljava.so look for this libjvm.so by explicitly putting
# cat /usr/local/libdata/ldconfig/openjdk
/usr/local/openjdk6/jre/lib/amd64/server
and therefore :
ldd /usr/local/pgsql/lib/pljava.so
/usr/local/pgsql/lib/pljava.so:
libjvm.so => /usr/local/openjdk6/jre/lib/amd64/server/libjvm.so (0x800c00000)
libc.so.7 => /lib/libc.so.7 (0x800648000)
libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x80178f000)
libm.so.5 => /lib/libm.so.5 (0x80199f000)
libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x801abf000)
libthr.so.3 => /lib/libthr.so.3 (0x801bcd000)
Also by doing :
dynacom=# SELECT PG_BACKEND_PID();
pg_backend_pid
----------------
20205
(1 row)
dynacom=# SELECT getsysprop('user.home');
^^^^^ hangs here, and from another shell :
% gdb /usr/local/pgsql/bin/postgres 20205

Without the explicit addition to the ldconfig in /usr/local/libdata/ldconfig/openjdk pljava.so had problems
loading it.
