"The Java Virtual Machine is the cornerstone of the Java platform. It is the component of the technology responsible for its hardware- and operating system-independence, the small size of its compiled code, and its ability to protect users from malicious programs."

"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.
Kind of strange that such experience still allows for WASM to be the target of C and C++ compilers, and there is no bounds checking support inside linear memory regions.
WASI is a standard on where to poke holes on the sandbox for your specific use-case
WASM+WASI as a compilation target allows any program written for modern operating systems to work on any WASM runtime
