Getting a NPE
Caused by:
java.lang.NullPointerException

The debug logging code from JavaBeanDispatcher getting serviceInstance as null .
Issue seems to be in the below mentioned code snippet.
if (log.isDebugEnabled()) {
log.debug("Exception invoking a method of " +
serviceImplClass.toString() + " of instance " +
serviceInstance.toString());
To fix this, we can change the
log.debug("Exception invoking a method of " +
(serviceImplClass == null : null ? serviceImplClass.toString() ) + " of
instance " + (serviceInstance == null : null ? serviceInstance.toString()));
In the original code is it necessary to call toString() in the log statement
since toString() will anyways be called when serviceInstance is not null.
