Subject [jira] Resolved: (AXIS2-2495) JAX-WS Performance (SpineImpl should close XMLStreamReader)
Date Tue, 10 Apr 2007 17:16:32 GMT


Rich Scheuerle resolved AXIS2-2495.

    Resolution: Fixed

Revision 527205

> JAX-WS Performance (SpineImpl should close XMLStreamReader)
> -----------------------------------------------------------
>                 Key: AXIS2-2495
>                 URL:
>             Project: Axis 2.0 (Axis2)
>          Issue Type: Bug
>            Reporter: Rich Scheuerle
>         Assigned To: Rich Scheuerle
> The JAX-WS XMLSpineImpl code uses an OMSourcedElement to store the data (normally a JAXB
object) in the OM
> tree.
> During performance analysis we realized that even though the code is pulling all of the
body events to create the JAXBElement, 
> the remainder of the events in the message are not pulled.  This means that the XMLStreamReader
(and ultimately the parser) is never closed.
> Failure to close the parser can result in severe performance penalties, which are dependent
on the parser implemenation.  For example, the parser may not adequately free its resources.
> Prior to these changes, I tagged the code in XMLSpineImpl with a TODO statement to review
the code.
> In a few minutes I will commit the real fix.  This should not cause any logical differences.
> Thanks,
> Rich
