That gist of it is that some companies are breaking with Sun and
trying to establish a standard for Java in real time systems.

I remember being at a Alsys demonstration once where one of the Ada
compiler writers warned against using exception handling in hard real
time systems because you couldn't guarantee how long it would take to
unwind to find the handler for the raised exception.  I wonder if such
conditions esist for exception handling in Java?  (Or dynamic
dispatch, for that matter)
