RFR: 7130985: Four helper classes missing in Sun JDK

[Rob McKenna]

Hi folks,

Looking for a review for the following:

bug: https://bugs.openjdk.java.net/browse/JDK-7130985
webrev: http://cr.openjdk.java.net/~robm/7130985/webrev.01/

As per the bug report: The IDLtoJava spec clearly specifies the need of 
the helper class (not the Holder) for these files. But these are absent 
in the JDK. So, if we try to send any of these classes across in a 
client-server rmi-iiop model, it will throw an error complaining about 
the absence of the helper class.
