Is this at this point a philosophical discussion on what "code execution" means? I suspect not but citing JVM interpreting bytecodes would make it one. :-)
As I understand it the real restriction is not being interruptible (for I/O). In which case a clever (and aren't they all nowadays?) :-) JVM might well find itself executing machine code that you'd hope wouldn't have to be copied below the bar first.

That's my understanding. Also, I've stumbled into at least one non-IBM product that is already executing code above the bar. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM z Systems, AP/GCG/MEA E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
