I can see why this is failing, but I have not been able to duplicate it.
It is trying to turn the md5 salt into a String. The problem is that
random bytes don't always make a string depending on your encoding (which
I'd be interested to know.) I've attached a patch to the 7.4 driver which
I believe should fix this problem. I've also put a prebuilt version of
this up at
http://www.ejurka.com/pgsql/jars/pg74jdbc3-nadeem-bitar.jar
Please let me know your jvm encoding and if this fixes the problem.
