%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>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
