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. -- Waldek Hebisch
