Description

When invoking several different web services asynchronously a NullPointerException is raised. The web services were invoked firstly in parallel later sequentially. The issue occurs more frequently when the web services are executed in parallel.

Apparently the issue is at ClientImpl line 715 in version 2.4.4. I've debugged the issue and in some executions bus is null on method onMessage:

public void onMessage(Message message) {

Endpoint endpoint = message.getExchange().getEndpoint();
if (endpoint == null)

{ // in this case correlation will occur outside the transport, // however there's a possibility that the endpoint may have been // rebased in the meantime, so that the response will be mediated // via a set of in interceptors provided by a *different* endpoint // endpoint = getConduitSelector().getEndpoint(); message.getExchange().put(Endpoint.class, endpoint); }

message = endpoint.getBinding().createMessage(message);
message.getExchange().setInMessage(message);
message.put(Message.REQUESTOR_ROLE, Boolean.TRUE);
message.put(Message.INBOUND_MESSAGE, Boolean.TRUE);
===> PhaseManager pm = bus.getExtension(PhaseManager.class);

This is the exception raised:
