Open CMIS not supporting IBM Websphere JAX-WS

We are running two existing web services in our environment and both are using IBM Websphere JAX-WS engine. Because of this we have tuned the IBM Websphere JAX-WS engine to get Maximum throughput as per our requirements. The CMIS Server which was developed using OPENCMIS server framework is dependent on SUN JAX-WS engine.

All our client application consumes two existing web services and the new CMIS Web service. But Websphere runtime restricts the usage of application modules that use both IBM's JAX-WS implementation and an external JAX-WS implementation in the same application.

So, is there a way for OPENCMIS Server Framework and OPENCMIS Client Framework to make it work with IBM Websphere JAX-WS engine without any dependencies on Sun JAX-WS?
