Description:
Fixing Bug #1913 to make TINYINT and SMALLINT to return Integer types was not accompanied
by 
needed correction to ResultSetMetaData.getColumnClassName(), which should return
java.lang.Integer

How to repeat:
For a TINYINT or SMALLINT in a ResultSet:

ResultSetMetaData.getColumnClassName()

Suggested fix:
    public String getColumnClassName(int column) throws SQLException {
        Field f = getField(column);

        switch (f.getSQLType()) {
        case Types.BIT:
            return "java.lang.Boolean";

        case Types.TINYINT:

             return "java.lang.Integer";

        case Types.SMALLINT:

             return "java.lang.Integer";
