> This patch is submitted by Lizet Ernand and Rich Scheuerle.
> Lizet Ernand is an IBM Web Services developer whose responsibilities include
> JAXB marshalling,
> StAX processing and JAX-RPC/JAX-WS tooling. She has over 5 years experience
> in Web Service Development.
> ==============================================
> Description of Changes:
> Correct OMStAXWrapper.getProperty(String s)
> -------------------------------------------
> According to the StAX specification, the getProperty(s) method should return
> the requested property from the parser.
> The patch contains a simple change to delegate this method to the underlying
> parser.
> Use Case:
> a) The JAXB unmarshalling code calls getProperty on the XMLStreamReader.
> b) The actual XMLStreamReader is an OMStAXWrapper supplied by Axiom.
> c) The OMStAXWrapper should delegate the getProperty call to the underlying
> parser (if one exists).
> Track of Parser Closure State
> -----------------------------
> Unfortuanately, the StAX specification does not provide an isClosed() method
> on the XMLStreamReader.
> However, we can easily track this information in the StAXBuilder and
> OMStAXWrapper.
> Use Case:
> Some methods on the parser are not available when the parser is closed.
> Knowing the closure state can
> help in these situations.
> Release Parser On Close
> -----------------------
> Currently the StAXBuilder and OMStAXWrapper never relinquish the parser
> object. Thus the Axiom tree maintains a
> reference to the parser long after it is needed.
> Depending on the parser implementation, this can cause out of memory
> situations.
> Code is added to support "releaseParserOnClose". When this setting is in
> effect, the parser object will be freed
> during on close.
> The default for "releaseParserOnClose" is the current behavior.
> ==================================
> The patch only affects StAXBuilder and OMStAXWrapper. A test is modified to
> validate the changes.
> I am submitting the patch, and will commit it this afternoon.
> Thanks,
> Rich
