(Un)Fun with Java - Memory leaks by design... = bad design.

ObjectOutputStream oos = new ObjectOutputStream(...);
...
write lots of objects to the ObjectOutputStream.

get OutOfMemory exception :-(.

ObjectOutputStream keeps a record of every object it has seen, and thus prevents the object from being garbage-collected, even when you ARE done with it.
