> Imagine you have the flowing context "a/b/object". The context tree can be created in two ways:
> 1. Relative to the root or some
> {code} 
> IvmContext root = IvmContext.createRootContext();
> root.bind("a/b/object", new Object);
> {code}
> 2. Relative to some node:
> {code}
> IvmContext root = IvmContext.createRootContext();
> root.bind("a", null);
> IvmContext a = root.lookup("a");
> a.bind("b", null);
> IvmContext b = root.lookup("b")
> a.bind("object", new Object())
> {code}
> So when one looks up "object" or "a" or "b" or object, one has to get the very same result regardless if the context tree was created by 1 or by 2. Yet this is not the case when it comes to the IvmContext. Maybe the most obvious (and shocking) issue is that IvmContext allows to bind 2 different objects to the same name ! Example:
> {code}
>        IvmContext root = IvmContext.createRootContext();
>         root.bind("a/b/object", new Object());
>         IvmContext b = (IvmContext) root.lookup("a/b");
>         //already bound from root -> must fail, yet it does not
>         b.bind("object", new Object());
> {code}
> I've provided various test cases for different combinations of bind/unbind/lookup that reproduce the issue.
