A DESCRIPTION OF THE PROBLEM :
Unexpected exception is raised when using DII and receiving user exception which has a string with non Latin-1 chars.

com.sun.corba.se.impl.protocol.CorbaMessageMediatorImpl unmarshalDIIUserException
WARNING: "IOP00710244: (INTERNAL) Unexpected exception while unmarshalling DII user exception"
Caused by: org.omg.CORBA.DATA_CONVERSION: vmcid: OMG minor code: 1 completed: No



STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Force native string charset to UTF-8:
props.setProperty("com.sun.CORBA.codeset.charsets", "0x05010001");

Make dynamic call to method that raises user exception with string property containing non Latin-1 character.

The unmarshalDIIUserException method at CorbaMessageMediatorImpl.java:453 tries to wrap user exception from CDR stream into Any object using default EncapsOutputStream.
That stream has ISO8859-1 charset as default.

If user exception has string with non Latin-1 character then java.nio.charset.UnmappableCharacterException occurs.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
User exception thrown to application context
ACTUAL -
Unexpected Internal exception

REPRODUCIBILITY :
This bug can be reproduced always.
