  Even better was a complete system rather than a mode for arm processors that ran a subset of the common jvm opcodes. https://en.wikipedia.org/wiki/PicoJava https://en.wikipedia.org/wiki/PicoJava

  Didn't some phones have hardware Java execution or does my memory fail me?

    It's called Jazelle.

      Sun tried to build one too, they called it the JavaChip iirc. It was meant for JavaStations, kiosk machines, and mobile phones but it never took off. https://en.wikipedia.org/wiki/Java_processor https://en.wikipedia.org/wiki/Java_processor

      No. There where Motorola phones with Motorola processors with Java Co-Processor. Not Jazelle.

    Yes. I known at least one Motorola phone which had a co-processor for Java (not Jazelle)
