Thanks for using Derby!

Your program also fails for me. The exception stack trace that
I receive is:

performing dump.
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

Line 1047 of NetCursor.java is the assignment to the "data" variable
in this code:

     protected byte[] findExtdtaData(int column) {
         byte[] data = null;

         // locate the EXTDTA bytes, if any
         Integer key = new Integer(column);

         if (extdtaPositions_.containsKey(key)) {
             //  found, get the data
             int extdtaQueuePosition = ((Integer) extdtaPositions_.get(key)).intValue();
             data = (byte[]) (extdtaData_.get(extdtaQueuePosition));
         }

         return data;
     }


This looks like a bug to me. I think you should open a JIRA
issue and attach your program as a test case.
See http://db.apache.org/derby/DerbyBugGuidelines.html
for more information about how to do this.
