From the same link, opening sentence:
"The Java® programming language is a general-purpose, concurrent, object-oriented language."
Edit: Having thought a little, I appreciate that it's possible to compile for the JVM from source code which is not Java, which makes the JVM a compilation target. As far as I'm aware the JVM doesn't have first class support for this though, It's been tacked on as an afterthought. Compiling C to JVM bytecode for example doesn't appear to be an enjoyable process. WASM on the other hand was designed explicity to function as a compilation target for arbitrary languages.
Maybe I'm missing something, happy to be proven wrong.
There are (or have been) lots of languages using the JVM as a compilation target, whether it is well-suited for this or not. Wikipedia has a partial list: https://en.wikipedia.org/wiki/List_of_JVM_languages
My point is that it isn't well suited for it. Hence WASM.
