This indeed seems to have changed in Xerces v1.5.1. I was able to
successfully use same instance of parser, even after generating
exceptions.

I would invite comments from someone from Xerces development ( apache.org
or ibm.com ) to autheticate our findings.

With single instance of parser, you can can parse() multiple times.  The
parser in fact will call 'reset()' internally everytime, so you don't really
need to call 'reset()' before re-use.
