NPE when ResultSet is null

[vladchuk]

In the DefaultResultSetHandler, where rs is null (Oracle returns null RS in certain cases), a nasty NP exception is thrown (in the ResultSetWrapper) below:

private void handleRefCursorOutputParameter(ResultSet rs, ParameterMapping parameterMapping, MetaObject metaParam) throws SQLException {
try {
final String resultMapId = parameterMapping.getResultMapId();
final ResultMap resultMap = configuration.getResultMap(resultMapId);
final DefaultResultHandler resultHandler = new DefaultResultHandler(objectFactory);
final ResultSetWrapper rsw = new ResultSetWrapper(rs, configuration);
handleRowValues(rsw, resultMap, resultHandler, new RowBounds(), null);
metaParam.setValue(parameterMapping.getProperty(), resultHandler.getResultList());
} finally {
// issue #228 (close resultsets)
closeResultSet(rs);
}
}

It would be nice to have a check, something like:
if (rs != null) {
final ResultSetWrapper rsw = new ResultSetWrapper(rs, configuration);
handleRowValues(rsw, resultMap, rh, new RowBounds(), null);
}

Please fix or suggest a workaround - this really makes it impossible for us to use mybatis.

Hi,

It should be fixed in the latest 3.4.0-SNAPSHOT.
As I don't have Oracle environment at hand, I would appreciate if you could test it with your solution.
