You'd be best off to inquire about that on the pgsql-jdbc mailing list.
This list deals with issues in the core server, which I doubt that is.

FWIW, you might want to double-check that you've not accidentally
changed any connection parameters.  It could be useful to enable
log_connections on the server, so you can see if the connection
attempts look any different in the server log.
