RFR: 7199858: Marshal exception is wrong

[Dmeetry Degrave]

Hi,

Resending a code review request for a corba fix for 7 and 8, which is 
identical to fix went to earlier releases.

A wrong unexpectedUnionDefault exception is thrown in TypeCode handling 
code when an OptUnion value with false discriminator is inserted into 
any of NV struct on server side for the following idl:

union OptUnion switch (boolean) {
    case TRUE:
       unsigned short opt;
};

struct NV {
       string name;
       any value;
};

typedef sequence<NV> NVSeq;

interface OptUnionInterface
{
    OptUnion retrieve ();
    NVSeq retrieveNVSeq();
};

The fix is elimination of the exception, as it's wrong. There is a test 
case attached to the bug, though it requires a CORBA env setup.
