ScriptExpressionEvaluator does not throw Exception

Let's assume that I wanted to do some logic in groovy expression when inserting data to database. I have following jdbc-endpoint query configuration:

<jdbc:connector name="foo-connector" dataSource-ref="foo-ds">
  <jdbc:query key="insertFoos"
            value=" INSERT INTO FOO
                    (field1,
                     field2)
                    VALUES 
                    (#[groovy:payload.bar],
                     #[groovy:throw new RuntimeException('field2 gets inserted with null instead of error in JdbcMessageDispatcher')])" />
</jdbc:connector>

For simpler example I omitted the actual logic by throwing an Exception intentionally.
When I call the endpoint, no Exception is thrown to Mule. Only null value is inserted in the database. I think it is very dangerous if an Exception is not thrown when evaluating an expression. Now corrupted data may be added to database.

I think the cause is in

public Object evaluate(String expression, MuleMessage message)
{
        Scriptable script = getScript(expression);
        script.setMuleContext(muleContext);
        Bindings bindings = script.getScriptEngine().createBindings();
        script.populateBindings(bindings, message);

        try
        {
            return script.runScript(bindings);
        }
        catch (ScriptException e)
        {
            return null;
        }
}

The ScriptException is omitted brutally. Could the exception be propagated so I would sleep better at nights?
