RE: [EXTERNAL] Re: CXF Servlet NPE in PerRequestFactory.create(PerRequestFactory.java:56)

Not sure what the culprit was either, but did a full upgrade to 3.1.12 and all is well.

This is the part that looks very suspect to me:

> TTPDestination.java:262)

First:  the  ChainInitiationObserver.java line doesn’t have a line number yet the others do.   That looks very troubling.  Also makes it hard to figure out what it’s doing.

Second: looking in ChainInitiationObserver, there is NO call to getServiceObject.   I traced back through and I don’t see that call ever in any version of ChainInitiationObserver.  Thus, I have no idea what’s going on.   I would definitely check to make sure you are using proper versions of CXF released by us at Apache.
