This method is called to obtain the memory manager that should be used to allocate memory used in exceptions.
<p>
If the same memory manager can be used, simply return 'this' from this function. Note, however, that if there is a possibility that an exception thrown can outlive the memory manager (for example, because the memory manager object is allocated on the stack or is managed by a stack-bound object), it is recommended that you return <a class="el" href="classXMLPlatformUtils.html#97eff0d9fff3567bea3acd3ca4d95252" title="The configurable memory manager.">XMLPlatformUtils::fgMemoryManager</a>.<p>
