Description

This bug is similar to CXF-2591 but relates to sync clients.
A simple client using a service with WS-Addressing which makes repeated calls to a service that returns a soapfault will cause a build up of objects in MAPCodec::uncorrelatedExchanges.
The real use case is an application using Apache Camel to keep invoking a service that returns a fault (for instance wsa:DestinationUnreachable) using the built in redelivery-functions of Apache Camel.
A simple CXF client that reproduces the issue has been created. The client just invokes a service in a loop and by observing the used memory (jconsole) and performing memory dumps which can be analyzed using MAT, you can see the issue.
A standalone wiremock functions as the endpoint.
The reproducers will be attached.
