I write programs for a living, and in the real world a good debugger is 
essential.  But I have found them surprisingly unhelpful to GCJ style 
programming contests.  In the real world, most code problems seem to occur in 
large complicated chunks of code that are executed 1 to maybe 5 times.  In 
programming contests there is a lot less code, but those lines are typically 
run from anywhere to hundreds to tens of thousands of times.  Debuggers can 
be used in that environment, but it gets a lot harder and is generally easier 
to fall back on the time honored debugging technique of just adding print 
statements.
