AbstractJAXBProvider: getJAXBUnmarshaller is final (unlike getJAXBMarshaller)

I am extending AbstractJAXBProvider and found that getJAXBUnmarshaller is final (unlike getJAXBMarshaller). It is just inconsistent and would be useful if these methods are not final.

I am actually more interested in overriding AbstractJAXBProvider#getXMLStreamReader(...) calls and these are marked as static. It would be useful if these methods are not static. I can then wrap the XMLStreamReader to deal with XML parsing case sensitivity issues like:

javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"Time"). Expected elements are <{}time>

Simple changes:
a.) Remove final keyword on AbstractJAXBProvider#getJAXBUnmarshaller()
b.) Remove static keyword on AbstractJAXBProvider#getXMLStreamReader(InputStream) and AbstractJAXBProvider#getXMLStreamReader(InputStreamReader)
