[8u$N] Request for enhancement backport approval for CR 8164908 ReflectionFactory support for IIOP and custom serialization

[Roger Riggs]

Please approve the backport of enhancements to 
sun.reflect.ReflectionFactory[1] to facilitate
the transition of custom serialization libraries to the strong 
encapsulation in JDK 9.

The methods added to ReflectionFactory are used as replacements for the
use of setAccessible to access private methods specific to serialization.

The risk is minimal for JDK 8.
   The new methods have been implemented in JDK 9 and are used by the 
JDK 9 IIOP implementation.
   Tests for the new APIs are included in JDK 9 and are included in the 
backport.
   To minimize risk to JDK 8, the IIOP implementation is not modified.

Thanks, Roger
