> IIRC the ARM-9 was Jazelle that did the most "Java bytecode as native instructions", and there was a GNAT-JVM (IIRC GNAT Community release circa 2014) that targeted the JVM, which was Ada 2005 and [slightly buggy, iIRC] Ada 2012 ? hence it could be possible to run JVM-targeted Ada 2005/2012 natively on such a processor.

Is there real hardware implementing Java bytecode?  My impression was
that the whole thing was mostly software.  It is not clear to me
if it has any advantages compared to different JVM.  IIUC there
is clear disadvantage: Jazelle need software support integrated
at low level with OS.  It is not clear to me if ARM Linux has
needed support.
