RE: Random ArrayIndexOutOfBoundsException
We got a very similar looking problem with a different jdk and different app server (but as well cocoon 2.0.4). Difference was that the exception was not in endElement but in comment. We never really traced it down. I happended only on one certain page, and after we restructured it a bit the problem vanished -Original Message- From: Gabriel Egolf [mailto:[EMAIL PROTECTED] Sent: 25 June 2003 20:48 To: [EMAIL PROTECTED] Subject: Random ArrayIndexOutOfBoundsException Hello all.

Re: Random ArrayIndexOutOfBoundsException
Sadly, I don't think it's gonna be a fix for this problem. I ran the Environment Check stylesheet and it looks like my servlet engine is using the correct Xalan version - 2.3.1. I'll attach the relevant XML output at the end. There was an observation that I might have some threadsafe coding problems. Most of the errors appear in pages where simple transformations (XML + XSL - XHTML) are happening. I really am rather at a loss.
