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, given server side
received 10000 messages through http
jmap -histo:live 7595|grep cxf

> 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)

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