%X Object Oriented languages have increased in popularity
   over
the last two decades. The OO paradigm claims to model
   the way
objects interact in the real world. All objects in
   the OO model
are passive and all methods are executed
   synchronously in the
thread of the caller. Active objects
   execute their methods in
their own threads. The active
   object queues method invocations and
executes them one at a
   time. Method invocations do not overlap,
thus the object
   cannot be put into or seen to be in an inconsistent
state.
   We propose an active object system implemented by
   extending
the Java language with four new keywords:
   <code>active</code>,
<code>async</code>, <code>on</code> and
   <code>waitfor</code>.
We have modified Sun\[rs]s
   open\-source compiler to accept the
new keywords and to
   translate them to regular Java code during
desugaring phase.
   We achieve this through the use of RMI, which
as a side
   effect, allows us to utilize a cluster of work stations
to
   perform distributed computing
