Thanks for the reply. For the record I confirmed this error happens on xercesImpl-2.12.2.jar.
While I too am somewhat amazed this cast ever worked, it did actually work for 10 years starting on this Rampart commit below. " commit b73690eefaad9027bb9633a20e29a218a1021cc9 (HEAD -> master) Author: Amila Jayasekara <ami...@apache.org> Date: Thu Mar 8 08:11:32 2012 +0000 Refactored SAML2TokenIssuer and cleaned up code. Created a test framework to write unit tests for trust scenarios. Fixed documentation errors. Reduced code duplication. Added more tests. " I see that OMNode at runtime ends up being an Axiom class DOOMNSAwareElementImpl that "extends CoreElementImpl" , which implements "org.w3c.dom.Element" - that to me explains why it compiles. So, this is a runtime issue on code that worked fine for a long time. Before I figure out how to rewrite the code in question as I'm not really sure, I thought I'd ask why this happened all of sudden on the Xerces side as I have no clue on the Axiom side.
