Hi there,

I'm using Xerces in my webapp to parxe XHTML stuff, everything goes fine most 
of the time, but sometimes (I yet don't have a reproducable case, it just 
"happens", I hate that kind of bugs) I meet the exception said above.

It happens on xerces 2.0.2 (bundled with tomcat 4.1.9), xerces 2.3 (the one 
bundled with tomcat 4.1.24).

Here's the stacktrace on xerces 2.0.2

java.lang.ArrayIndexOutOfBoundsException

http://cvs.apache.org/viewcvs.cgi/xml-xerces/java/src/org/apache/xerces/impl/XMLEntityManager.java?rev=1.25&content-type=text/vnd.viewcvs-markup

I have no idea of what's happening. I know this is a old release of Xerces but 
didn't find any related bug in mail-archives/bugzilla/newsgroups/whatever :(

I don't want devs to spend time on it, but if anyone has an idea of where it 
may come from ?

I've seen in release notes that 2.5.0 has this line :

* Fixed an ArrayIndexOutOfBoundsException in the scanner caused by some invalid 
character references. [Michael Glavassevich] 

but didn't find related bug in bugzilla, and I have no idea if this is the same 
or not ???

If it speaks to someone here... :)

Thx,
Aurelien
