RFR: JAXP in JDK8/7u40 : 8021148 Regression in SAXParserImpl in 7u40 b34 (NPE)

Hi Lance, Chris,

Looking at the affected class [1], and the error stack trace [2] , it 
appeared that in SAXParserImpl$JAXPSAXParser , line 545, 
fSAXParser.fSecurityPropertyMgr is null when setProperty is called. 
fSecurityPropertyMgr was instantiated in SAXParserImpl's constructor 
after JAXPSAXParser was.  I can see a chance where the NetBeans got a 
copy of JAXPSAXParser instance with fSecurityPropertyMgr not 
initialized.  The fix is to remove the reference of fSecurityPropertyMgr 
in JAXPSAXParser, and pass it in when JAXPSAXParser is created.

Here is the webrev:
