----------------------------

       Resolution: Fixed
    Fix Version/s: 2.2
                   2.1.5

Use a static filed transformerFactory in the WSDLQueryHandler to keep the factory reference,
so the implemention searching only occurs while the first time the class in initialzed.
Commit changes to trunk at revision: 777366, 2.1.5-snapshot at revision: 777367.

> I've a typical web-service  that gets polled every N minutes, I noticed that when it
is servicing a request the CPU usage is hitting close to 80%. I expect to have multiple clients
to this web-service so it is going to be a problem. 
> Based on what I deduced, the following stack trace is trying to load several of JAR files
and not able to load/find them. This is resulting in lot of kernel level calls thus CPU utilization.
