Freeman Fang updated CXF-2975:
------------------------------
Attachment: testcase.patch
> ChainInitiationObserver lack synchronization which could causes
> continuations to malfunction for some rare scenario
> --------------------------------------------------------------------------------------------------------------------
>
> Key: CXF-2975
> URL: https://issues.apache.org/jira/browse/CXF-2975
> Project: CXF
> Issue Type: Bug
> Affects Versions: 2.2.10
> Reporter: Freeman Fang
> Assignee: Freeman Fang
> Fix For: 2.3, 2.2.11
>
> Attachments: testcase.patch
>
>
> If we call continuation.resume in another thread after we call
> continuation.suspend immediately, we may encounter a situation where resume
> is called on continuation before the SuspendedInvocationException causes
> PhaseInterceptorChain to change state to 'paused', so that
> ChainInitiationObserver instead of resuming the the PhaseInterceptorChain
> from where it was suspended, it starts it's from the beginning. This is
> incorrect as interceptors that has already been run are called again in this
> case.
> With this attached testcase which expose this problem, simply use
> continuation api in a jaxws provider, we can see the
> IncomingMessageCounterInterceptor get invoked twice for one incoming messsage.
