"Best" Pre-compiled driver for PostgreSQL 7.2.2 ?

Hi, all.

 From the download page (jdbc.postgresql.org/download.html), I am trying 
to determine which driver to use for my 7.2.2 engine.  It looks like 
there may be two options.  I have a 1.3 JDK.

pg73jdbc2.jar

pg72jdbc2.jar

The 73 version says it "supports 7.1 and 7.2".

I originally compiled the JDBC driver from the 7.2.2 source.  It worked 
okay, but we are now trying to track down some bugs. We are getting null 
pointer errors and possible deadlocking situations.  It is possible that 
the JDBC driver is playing a role, so we want to try a pre-compiled version.

Any help would be greatly appreciated.
