[ http://issues.apache.org/jira/browse/XALANJ-1914?page=comments#action_12441168 ] Henry Zongaro commented on XALANJ-1914: ---------------------------------------
Hi, Hamed. The ArrayIndexOutOfBoundsException looks like it's being thrown by FOP, rather than Xalan-J. It's possible that Xalan-J is the root cause of the problem, but I'd suggest you report this against FOP initially as it appears to be unrelated to the problem described in this bug report. Thanks, Henry. > Transformation failure in Multithread environment. > javax.xml.transform.TransformerException: 5 >= 1 > ---------------------------------------------------------------------------------------------------- > > Key: XALANJ-1914 > URL: http://issues.apache.org/jira/browse/XALANJ-1914 > Project: XalanJ2 > Issue Type: Bug > Components: transformation, Xalan-interpretive > Affects Versions: Latest Development Code > Environment: Operating System: Windows NT/2K > Platform: Other > Reporter: Yash Talwar > Assigned To: Yash Talwar > Priority: Blocker > Fix For: 2.7 > > Attachments: patch.txt > > > Using the currentCVS version of XalanJ2. > When I run transformation using single thread, it works fine. > When multi threads are using for the transformation using the same xml file > and > xsl file that is used in single thread test, I get various symptoms.
