I have done alike the discription Steps to add any new JSF implementation or version to WildFly on WildFly 8.1.0 final and test ist with the  provided test application there for

• mojarra-1.2_15 which works as expected
• myfaces-2.1.14 which works as expected
• myfaces-1.2.12 which produces exception while deployment, and is marked deployment failed.

MyFaces 1.2.12 is an implementation of Faces 1.2, so I would expect, it is  working at WildFly.

Am i right?
