Hi Michael
Thanks for your help.
ArrayIndexOutOfBoundsException thrown from UTF8Reader.read with the
following stack trace is fixed in the latest Xerces jar and we a code
fix for xerces 2.7.1 jar also
java.lang.ArrayIndexOutOfBoundsException: 2048

However I don't know whether the ArrayIndexOutOfBoundsException
exception thrown from XMLEntityScanner.skipSpaces has been fixed in the
latest Xerces jar. We don't have a stand alone program to replicate this
exception, hence haven't been able to test it

I assume both ArrayIndexOutOfBoundsExceptions are thrown from different
methods within the different classes, hence their fix should also be
different. We are frequently getting the latter exception, hence need a
standalone program that can be used to replicate it. Can you help us
regarding this?

Hi Ankur,
You say you can't upgrade to the latest version of Xerces, but have you
at
least tried testing whether this bug was fixed? When I execute your test
with Xerces-J 2.9.1 it runs fine. Most likely fixed by this commit [1].
Thanks.
