[jboss-jira] [JBoss JIRA] (AS7-1485) Packaging Xerces in war causes JSF ClassCastException on SAXParserFactory

[Jason Greene (Commented) (JIRA)]

    [ https://issues.jboss.org/browse/AS7-1485?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12634676#comment-12634676 ] 

Jason Greene commented on AS7-1485:
-----------------------------------

I'm not sure where the source for that release came from but I assume it was this:

https://github.com/jboss/mojarra/commit/7c3c8a62c0af019c61e61615f82ba10fedd44c07  ?

The problem seems to be that the patch is too broad, the TCCL swapping should be wrapped around just JAXP factory instance creation and no wider.
