What version of the driver are you using? I see this in the CVS logs:

so if your driver is older than that, it may be the problem.
Failing that, are you using crypt-based authentication? ("crypt" in the
appropriate access line in pg_hba.conf). From a quick glance at the code
it looks like the crypt salt suffers from the same problem as md5 used
to -- it tries to turn a couple of bytes into a String using the default
encoding, which will not work reliably. As a temporary workaround, try
changing pg_hba.conf to use "md5" instead of "crypt".
If you use a different default encoding such as ISO-8859-1 (IIRC you can
do this by setting the file.encoding system property, i.e.
-Dfile.encoding=ISO-8859-1) does the problem go away?
