Fixes are available

APAR status

Closed as program error.

Error description

When enableInProcessConnections is set in the Web Container,
and then one JAX-WS web service calls another in a stack,
both can run on the same thread and some thread state data
might be lost.

Local fix

```
Set enableInprocessConnections = false
```

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server using JAX-WS web services and        *
*                  inProcessConnections                        *
****************************************************************
* PROBLEM DESCRIPTION: Different web services running on the   *
*                      same thread might corrupt each others   *
*                      threadlocal data.                       *

* RECOMMENDATION:  Install a fix pack containing this APAR.    *
****************************************************************
When enableInProcessConnections is set in the Web Container,
and one JAX-WS web service calls another in a stack,
and both are in the same local JVM, both will run on the same
thread.  In some cases this can lead to loss or corruption of
threadlocal data.

Problem conclusion

Logic is added to detect this condition and not use the same
thread when the problem might occur.

If problems occur when enableInProcessConnections is active,
the JVM property jaxws.useSafeIPC should be set to true.  The
default value is false.

When set, web services calling each other in the same JVM will
not run on the same thread.

For information on setting a JVM property see:

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.31, 8.0.0.6, and 8.5.0.2  Please refer to the
