> In StAXOMBuilder and MTOMXMLStreamWriter (renamed from OMOutputImpl), XML{Input|Output}Factory is created just once now.
> It is great to reuse XMLInputFactory and XMLOutputFactory instance, I think.
> But I am not sure whether XMLInputFactory.createXMLStreamReader() and XMLOutputFactory.createXMLStreamWiter() have thread safety or not.
> It seems that JSR-173 StAX specification does not mention their thread safety.
> IMHO, strictly speaking, these factories can be broken if these methods are called concurrently.
> These methods can be enclosed by synchronized block, or a factory instance pool or something can be made.
