Nor did they sue ActionScript (Macromedia Flash's implementation of JavaScript), CoffeeScript (a separate language that compiles to JavaScript, and has a name very much evoking Java).
I don't see any reason why that would matter. The name "actionscript" does not have the word "java" in it.
The relavent part is they didn't sue anyone using the name "javascript". Even if they had a valid trademark (which i doubt) that doesn't prevent anyone from selling a similar product under a different name.
I was replying to that_guy_iain, who pointed out that Oracle didn't sue Microsoft for TypeScript. Notice that TypeScript does not have the word "Java" in it either.
