There were a few chips that supported directly executing JVM bytecodes. I'm not sure why it didn't take off, but I think it is generally more performant to JIT compile hotspots to native code.

It did take off just in a different direction:

To the point where most adult humans in the world probably own a Java-supported processor on a SIM card. Or at least an emulator (for eSIMs).

On example of a CPU arch used on JavaCard devices is the ARM926EJ-S that I believe can execute Java byte code.
