Java would be an example of a language with weaker OOP capabilities. Javascript can emulate classic OO inheritance and it also supports prototypical inheritance. Crockford covers this in his Good Parts book, and you can find stuff around the web.
This way I can say that Java supports OO inheritance and can emulate prototypal inheritance (this can be done in C# and I suspect in latest Java). I think the correct statement is that "JavaScript supports a simple OOP model".
