-----------------------------------------

             Summary: LUCENESUPPORT routines should check for NULL arguments
                 Key: DERBY-6596
                 URL: https://issues.apache.org/jira/browse/DERBY-6596
             Project: Derby
          Issue Type: Improvement
          Components: Tools
    Affects Versions: 10.11.0.0
            Reporter: Knut Anders Hatlen
            Priority: Minor


When the LUCENESUPPORT routines are called with argument value NULL where a NULL is not allowed, they fail with NullPointerExceptions. Example:

ij> call lucenesupport.createindex('app', 't', null, null);
ERROR 38000: The exception 'java.lang.NullPointerException' was thrown while evaluating an expression.
ERROR XJ001: Java exception: ': java.lang.NullPointerException'.

Here, the third argument (the column name) cannot be NULL. It would be nicer if it raised an error that said that the argument couldn't be NULL, since a NullPointerException looks more like an internal error.
