RFR : 7162902 / 6893617 Umbrella port of a number of corba bug fixes from JDK 6 to jdk7u/8

[Sean Coffey]

Hi,

I'm looking for a code review around the following corba changes. It 
turns out that we've a few bug fixes in corba area for jdk6 that were 
never forward ported to jdk7 or 8. The port is pretty much identical to 
what was used in JDK6. Some formatting and diamond operator changes 
introduced but that's about it. There were a few bug fixes to follow up 
on regressions around the initial fix but this umbrella port should 
cover all issues.

The initial bugs fixes were fixed under the "jets" category in the bug 
tool and that category entered read only mode over a year ago. Hence the 
requirement for a new bug ID.

The main bug fix is 6725987 which is an issue where references to the 
ORB were being kept after ORB.destroy was called.

An accompanying CNCtx fix in JDK repo is also made to correct an issue 
where the java.naming.corba.orb system property wasn't used correctly.

Corba testsuites run and no issues seen. I've also run some JCK testing 
and saw no issues.

http://cr.openjdk.java.net/~coffeys/webrev.6893617.jdk8/ (jdk)

The corba codebase code formatting seems to vary quite a bit. I've 
reformatted in a small number of areas but the whole corba repo probably 
warrants it's own clean up project at a later date.

regards,
Sean.
