Subject Exception with current CVS of 2.1
Date Thu, 14 Nov 2002 15:16:56 GMT

With the latest CVS of cocoon-dev 2.1, I am getting this exception  
(below) from TomCat4.1.12 when I access anything in cocoon webapp.

The problem seems to be : "java.lang.VerifyError: Cannot inherit from  
final class", while setting up xerces:  
"org.apache.xerces.impl.XMLNSDocumentScannerImpl.createContentDispatcher 
".


Is someone in the middle of working on something that may be causing  
this?

Thanks for any help.


regards Jeremy
