Specification excerpt:

...
public String getTableName(int columnIndex)
                    throws SQLException
Retrieves the name of the table from which the value in the designated column was derived.

Specified by:
getTableName in interface ResultSetMetaData
Parameters:
columnIndex - the first column is 1, the second is 2, and so on; must be between 1 and the number of columns, inclusive
Returns:
the table name or an empty String if no table name is available
Throws:
SQLException - if a database access error occurs or the given column number is out of bounds
...
---------- end-of-excerpt ---------------

Problem description
===================
The spec currently states that getTableName should return an empty string in the case if
no table name is available.

The implementation currently does return null in this case. Please address the mini test.

    
Minimized test:

     public static void main(String [] arg) {
         RowSetMetaDataImpl meta = new RowSetMetaDataImpl();
         try {
             meta.setColumnCount(3);
         } catch (SQLException e) {
             System.out.println( "Unexpected (0) "+e );
         }
         try {
             String output = meta.getTableName(2);
             System.out.println("output: "+output);
         } catch (SQLException e) {
             System.out.println( "Unexpected "+e );
