assert failure in MessageUtil, because exception thrown with too many parameters when handling
OutOfMemoryError
---------------------------------------------------------------------------------------------------------------

         Key: DERBY-1497
         URL: http://issues.apache.org/jira/browse/DERBY-1497
     Project: Derby
        Type: Sub-task

  Components: Network Client  
    Versions: 10.2.0.0    
    Reporter: Andreas Korneliussen
 Assigned to: Andreas Korneliussen 
    Priority: Trivial


If the VM throws a OutOfMemoryException, which is caught in:
NetStatementReply.copyEXTDTA:

    protected void copyEXTDTA(NetCursor netCursor) throws DisconnectException {
        try {
            parseLengthAndMatchCodePoint(CodePoint.EXTDTA);
            byte[] data = null;
            if (longValueForDecryption_ == null) {
                data = (getData(null)).toByteArray();
            } else {
                data = longValueForDecryption_;
                dssLength_ = 0;
                longValueForDecryption_ = null;
            }
            netCursor.extdtaData_.add(data);
        } catch (java.lang.OutOfMemoryError e) {     <--- outofmemory
            agent_.accumulateChainBreakingReadExceptionAndThrow(new DisconnectException(agent_,
                new ClientMessageId(SQLState.NET_LOB_DATA_TOO_LARGE_FOR_JVM),
                e));  <----- message does not take parameters, causing assert failure
        }
    } 

Instead of getting the message: java.sql.SQLException: Attempt to fully materialize lob data
that is too large for the JVM.  The connection has been terminated.
I am getting an assert: 
Exception in thread "main" org.apache.derby.shared.common.sanity.AssertFailure: ASSERT FAILED
Number of parameters expected for message id 58009.C.6 (0) does not match number of arguments
received (1)
        at org.apache.derby.shared.common.sanity.SanityManager.ASSERT(SanityManager.java:119)
