ArrayIndexOutOfBounds in XMLEntityManager$EntityScanner.skipSpaces()

[Pernoud Aurelien <ap...@sopragroup.com>]

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
	at org.apache.xerces.impl.XMLEntityManager$EntityScanner.skipSpaces(XMLEntityManager.java:2865)
	at org.apache.xerces.impl.XMLDocumentScannerImpl$TrailingMiscDispatcher.dispatch(XMLDocumentScannerImpl.java:987)
	at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:333)
	at org.apache.xerces.parsers.StandardParserConfiguration.parse(StandardParserConfiguration.java:529)

associated class was :
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

Hi Aurelien,

The fix you're refering to in the 2.5.0 release notes definitely isn't
related to the behaviour you're seeing.
