RFR: 8032908: getTextContent doesn't return string in JAXP

[Aleksej Efimov]

Hi,

Please, review the fix [1] for the Node.getTextContent() bug: 
https://bugs.openjdk.java.net/browse/JDK-8032908

Problem description:
When Node#getTextContent is called to get the text content of node which 
is passed to XSLT extension function, a string that contains text 
representation of current Node and its siblings does not return but 
'null' returns.

Testing:
JAXP regression tests were executed with no failures: test/javax/xml 
test/com/sun/org/apache/xml
The following JCK tests were executed without any related failures: 
api/xinclude api/xsl api/javax_xml api/org_xml xml_schema api/xinclude

Thank you,
Aleksej
