Then fact 1 is misleading too since Python handles the compilation
automatically without programmer's intervention while Java requires
someone to explicitely invoke the byte-code compiler.

I just don't understand what's all that fuss with this simple and
quite comparison of Java and Python. You can google this ng archives,
you'll find hundreds of posts saying the same thing, and everyone so
far seemed to be smart enough to understand that this had nothing to
do with the byte-code specifications, VM implementation and presence
or absence of a JIT compiler.

Anyway, I do maintain that what I said is 100% correct, 100% accurate
given the context, and 0% misleading unless you're clueless enough to
not be able to parse a single english sentence (in which case I just
can't help). As a matter of fact, this didn't seem to "mislead" the OP
into thinking such a thing.

Regards.
