Sounds like you have a memory leak in your program. Yes, it is possible to have memory leaks even in Java programs. All you have to do is to add objects to a collection type (map, set, list, etc) and then forget to remove them, or null all references to the collection.
There are several software tools available to assist in detecting such leaks. I personally use OptimizeIt although I'm not sure if it is still the best one out there. I think they have an evaluation version you can download. Alternatively you can try to find the leak with a debugger and/or print stataments.
