PK95012: A MEMORY LEAK OCCURS WITH AN JAX-WS WEBSERVICE THAT USES @RESOURCE WEBSERVICECONTEXT.

APAR status

Error description

A WebSphere Process Server test of the Service Component
Architecture (SCA) binding of JAX-WS discovered a memory leak.

The WebServiceContext for the JAX-WS application is holding
onto memory.  For this particular test, 77% of the memory is
held by the WebServiceContext objects.

Problem summary

****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server users of   *
*                  JAX-WS and WebServiceContext                *
****************************************************************
* PROBLEM DESCRIPTION: The WebServiceContext is holding onto   *
*                      memory.  This may cause an              *
*                      OutOfMemoryError error.                 *

****************************************************************
A customer may define a WebServiceContext variable
with an @Resource annotation.  The JAX-WS engine will
automatically set the WebServiceContext prior to a Web Service
method invocation.  (This automatic assignment is called
"resource injection".)  The Web Service code can access certain
properties from the WebServiceContext during the execution of
the web method.

Here is an example usage:

  @WebService(...)
  public class MyEchoImpl {

     @Resource
     javax.xml.ws.WebServiceContext ctx; // Engine will set ctx

     @WebMethod(...)
     public String echo(String in) {
        ctx.getProperty(...);  // User accesses ctx
     }
  }


Note: The information in the WebServiceContext (ctx) is only
valid during the execution of the web method (echo).

A customer notice that the WebServiceContext objects hold
memory resources.  In some situations, this may cause an
OutOfMemoryError error to occur.

Problem conclusion

The information inside of a WebServiceContext object is only
valid during the execution of the web method.  Code is added
to the JAX-WS web service engine to release the memory
resources after the web method completes and the JAX-WS
outbound handlers are executed.  Releasing the resources
solves the memory leak.

The fix for this APAR is currently targeted for inclusion in
fix pack 7.0.0.9.  Please refer to the Recommended Updates
