Hi Everyone,

I've just tried out the latest SVN xmlblaster (v1.2 #15163) and have run
into a few problems...

There are now 2 exceptions that come up that didn't happen with the previous
version (although the previous version had other issues).

1) It seems that there's something wrong the data such that the XML-RPC
   driver chokes on it.  This is something new (same clients as before
   and didn't show this behaviour on the old xmlblaster server).
 
   See first exception below.

2) A whole raft of NullPointer exceptions.

   As soon as we see one of these, we'll keep getting more until we stop
   and restart xmlblaster.  Up until then though, all is well.
