I feel like most of this complaint is about OOP, not java.
My point is to follow a dogmatic OOP approach (think all the nouns like Agent, Prompt, etc.) to model something rather sequential.
Simula 67, like Java, may fit into some newer OOP definitions that have come about over the years, but it was not considered OOP at the time of its arrival. The term OOP hadn't even been invented yet. And when OOP finally did get used for the first time, it most definitely did not refer to Simula 67. Where on earth did you get the idea that it did? Whatever gave you that idea was, frankly, nonsense.
Furthermore, message passing was the defining feature of OOP. Of course it was. That is the distinction OOP was calling attention to – what made OOP different from the other object-based languages that had been around for decades beforehand. Nobody was going to randomly come up with OOP out of the blue to describe a programming model from the long ago past. Method calling may be superficially similar, but OOP was coined to call attention to what difference there is.
You are, of course, quite free to come up with your own redefinition of OOP that includes Simula, C++, Java, whatever you wish. You would not be the first. However, as we are talking about the original definition, whatever you want to define it as does not apply. It is not your definition that is under discussion.
I'm guessing only Smalltalk rivals Java in OOP-ness, as in Smalltalk literally everything is an object, while in Java only most things are objects.
