Hello

I'm trying to integrate JSF2 & SWF 2.2(and later) and encounter the following exception in the log.
I've tried different combinations of the binaries(JSF 2.0.3, 2.0.6, 2.1), SWF(2.2.1, 2.3.1) without success.
This exception doesn't affect workflow and just annoying.
My final configuration: SWF 2.3.1, JSF 2.1.7, Spring 3.1, RichFaces 4.2.2

Please advise on possible solutions.
