Hunting down program freeze

I have a huge program that is occassionally freezing for no obvious reason. Best I can fiure is that swing EventListeners are causing an infinite loop of callbacks. There is no error message generated, and if I try to profile my project, the profiler is unable to keep up with the strain.

I'd like to figure out where the freeze is happening, but there is far too much code to add a lot of System.out.printf(). What can I do to track down any infinite loops?

I'm using NetBeans to develop.
