7u60 request for approval for JDK-8028215 - ORB.init fails with SecurityException if properties select the JDK default ORB

[Mark Sheppard]

Hi,
    this is a 7u60 request for approval for the
issue:
https://bugs.openjdk.java.net/browse/JDK-8028215

as per the webrev:
http://cr.openjdk.java.net/~msheppar/8028215/jdk7-dev/webrev/

This is a backport of a fix applied to JDK8

reviewed by: alanb, coffeys, mchung

This fix checks for default ORBImpl and ORBSingleton set via properties 
or System properties

This compliments an earlier fix for 8021257 
https://bugs.openjdk.java.net/browse/JDK-8021257
which introduce the pkg restriction on com.sun.corba.ie.** in the JDK ORB.
The fix 8028215 reduces certain back compatibility issues that may occur 
for WLS forms clients.


regards
Mark
