Tomcat 7 LifecycleBase.init

[dB .]

I have some unit test code that mocks a lot of Tomcat classes so that I can 
test a Tomcat Valve (code in http://waffle.codeplex.com). Switching to Tomcat 7 
is giving me some grief. I used to be able to do this:

            SimpleContext ctx = new SimpleContext(); // my class
            Realm realm = new SimpleRealm(); // an empty realm
            ctx.setRealm(realm);
            _somevalve.setContainer(ctx); // valve container
            _somevalve.start();

Now I am getting this

java.lang.NullPointerException

The problem is in MBeanUtils that assumes that a valid container object is 
passed into it (from ValveBase.getObjectNameKeyProperties). I tried to walk 
this code and I don't understand how I am supposed to setup container (and 
possible its parent(s)) to not get this exception.

What am I missing? Any help is appreciated,

Thx
