Rich Scheuerle resolved WSCOMMONS-315.
--------------------------------------
Resolution: Fixed
> StAXUtils loads a singleton XML*Factory. It should load a singleton
> XML*Factory per classloader
> ------------------------------------------------------------------------------------------------
>
> Key: WSCOMMONS-315
> URL: https://issues.apache.org/jira/browse/WSCOMMONS-315
> Project: WS-Commons
> Issue Type: Bug
> Components: AXIOM
> Reporter: Rich Scheuerle
> Assignee: Rich Scheuerle
>
> Problem Description:
> ------------------------------
> The XMLInputFactory.newInstance() method uses the current classloader to
> determine which version of STAX XMLInputFactory to load.
> The current StAXUtils.getXMLInputFactory() overrides this behavior and uses
> the classloader of StAXUtils instead of the current classloader.
> Unfortunately this makes it impossible for Axiom to use the STAX version
> defined by a different classloader.
> Note: This issue is equally applicable to XMLOutputFactory.
> Problem Solution:
> -------------------------
> The solution is to change StAXUtils.getXMLInputFactory to return a STAX
> XMLInputFactory for the current classloader.
> This will comply with the expected STAX behavior.
> A weak map of (key=ClassLoader, value = XMLInputFactory) will be maintained
> to try and preserve a singleton factory per classloader.
> There will be two ways for users to trigger the old behavior.
> 1) A new method will be added to change the policy:
> /**
> * Set the policy for how to maintain the XMLInputFactory and
> XMLOutputFactory
> * @param value (if false, then one singleton...if true...then singleton
> per class loader
> * (default is true)
> */
> public static void setFactoryPerClassLoader(boolean value) ;
> 2) New methods will be added to programatically request the policy.
> ie. getXMLInputFactory(boolean isFactoryPerClassLoaderPolicy);
> Note: The same solution will be applied for XMLOutputFactory.
