Java still doesn't have value types AFAIK. Meanwhile WASM started out as no-gc continuous memory VM.
Comparing WASM and JVM is like comparing a truck and a bus because they are relatively the same size, move at the same speed etc.
I mean sure you can load people in trucks and cargo into buses - and both have been done with JVM (eg. people built C compilers) and WASM (people are building GCed runtimes on top of it despite lack of GC support from platform).
Almost 30 years later nobody sane is running C on JVM and there were many attempts posted here over the years.
