Since Java runs eBay, is used to power most of the hundreds of
millions of SIM cards in your cellphones, protects most of the
security/healthcare smartcards of entire countries like taiwan, and is
going to be used for BMW's 100, 300, 500 and 600 series, and likely in
future 700-series, why not an aircraft carrier as well? ;-)

After nine years in the planning stages, Real-time Specification for
Java (RTSJ) is a few months away from general enterprise applications,
according to the the minds behind the work.
"This is not a small scale. This is real-time in the large sense of
the word," Gosling said during his keynote to developers at the annual
JavaOne show here. "This is for building big control systems like
power systems and aircraft carriers."
Gosling said Defense Advanced Research Projects Agency (DARPA) through
its Ovm research division currently has project on the table that
should be complete in about two months that uses a research
implementation of the RTSJ with version 1.4 of the Java Virtual
Machine (JVM) specification.
During his keynote, Gosling and current RTSJ steward Greg Bollella
demonstrated an inverted pendulum (which is like balancing a ruler in
your palm) using a cart on a fixed track. Though a program that
calculates the position of the cart every 5 milliseconds, the cart was
able to lift the stick and balance the rod up. The experiment is a
duplicate of the one that Sun sponsored in Shanghai.
