Hi Segery,
The memory leak problem of JMSContinuation is still there with your change,
same behavior by my test.
And for the HTTP continuations, below is the statistics

> Apparently JMS and HTTP continuations leak, here is a comment from Freeman
> (see CXF 2002) :
> But another issue I've found is the message leak problem with jms
> continuation, let's say the server side recieved 1001 message
> then I saw the class instance like (get it by "jmap -histo:live" with jdk6)
> instance_count size

> Btw, I also see same memory leak problem with cxf http continuation.
