Brad Maxwell commented on AS7-1485:
-----------------------------------

Yes, I think we have it worked out in EAP, I'll be back next week and will rebuild the JSF 1.2.15 for AS 7.  We found an additional problem area in JSF 1.2.x, calling methods like newDocumentBuilder / newSAXParser the Xerces code was doing some weird stuff where it picked a classloader then loaded classes from it, this didn't work in JBoss 5.x, however it does seem to work in AS 7 (JSF2), I suspect because the JBoss Modules is giving a different classloader.
