>         Environment: Struts 2.1.6, but no changes in 2.1.8

> There is a NullPointerException in the CheckboxInterceptor when parameters are null at the following line :
> Set<Map.Entry> entries = parameters.entrySet();
> I don't know if "theorically" it should check or not for null parameters, but the XWork interceptors check it, so I think Struts2 interceptors should also check for null parameters.
