REGRESSION
----------
This bug report starts with JDK 7b123. This appears to be a regression from
CR 6877056, which was fixed in JDK 7 b123. The regression also begins with
JDK 6u19 and CR 6877056 was delivered in JDK 6u19.

SYNOPSIS
--------
Enum exchanged as parameters using CORBA call results in Exception

OPERATING SYSTEM
----------------
Windows XP

FULL JDK VERSION
----------------
JDK 7 from b123 onwards
Java 6 from 6u19 onwards

PROBLEM DESCRIPTION
-------------------
When the enum class 'java.math.RoundingMode' is used as parameter in a remote method and tried to send across to other side using CORBA call, the call fails with an Exception.


REPRODUCTION INSTRUCTIONS
-------------------------
1.Compile the test
   a) javac EnumTest.java
   b) rmic -iiop EnumTest$ServiceImpl

2.Run the command
        java EnumTest

Expected result:
        Test should pass without throwing exceptions

Observed result:
        Exceptions as detailed below:
