RFR: JAXP 1.5 for JDK8/7u40: 8016648: FEATURE_SECURE_PROCESSING set to true or false causes SAXParseException to be thrown

[huizhe wang]

Hi,

There have been two revisions in JAXP 1.5 specification: 1)  the 
relationship between the JAXP 1.5 properties and 
FEATURE_SECURE_PROCESSING (FSP) is now a recommendation. It is up to the 
implementation to decide if it wants to restrict when FSP is set.  2) 
System properties will override that may have been set by FSP.

In the following patch, a JDK version detection code is added so that 
when FSP is set explicitly, for JDK7, there will be no restrictions, but 
for JDK8 and above,  the restrictions are on.

The effective order is changed so that JAXP 1.5 defined system 
properties will override that may be set by enabling FSP.

Please review:

Note that the patch is identical for JDK7 and 8, and I plan to ask 
approval for 7u40 integration.

Thanks,
Joe
