JAXP default implementation and JDK-8152063

[huizhe wang]

So specifying Layer is preferred solution. If a new method is needed 
however, (similar situation to using the method with ClassLoader), that 
would mean your users' applications are required to adapt to the new 
API. Would you expect that would happen or would you still have existing 
applications that can not be updated?
