That restriction was in the java license because java is
garbage-collected and the garbage collector can run at
arbittrary times and take however long it needs. Thus,
hard realtime is not a good idea with java. Whatever
faults java may have, that license provision was not an
admission by Sun of any defects, just features. BTW, I
don't see it in the license that comes with JDK 1.4101.
Why not IDK.
