Java heap size vs. OS memory

When we run our Java application the Java heap reports at 80MB but the
Windows task manager reports 111MB. What accounts for the difference?

Your application uses more memory than just the heap. The VM needs space to
work, your bytecodes are there somewhere also, thread administration, stacks
etc.
