Not to forget Java ME (or whatever it is currently called). I'd argue that it is by far the most successful of all these failed attempts because it still is on many (maybe most even?) smartcards.

Java by itself was supposed to be a simple and compact language for embedded systems.

AFAIK Java Micro Edition is mostly dead except for retrocomputing enthusiasts. Java Card is a reasonably big thing.

Right, Java Card was the thing I meant. ME was the other thing we had in the half-smart phone era.
