Submission + - JavaToolbox.com tool: CollectionSpy (javatoolbox.com)
SoftwarePearls writes: It's not everyday Java sees a new profiler launched for it. CollectionSpy is a profiler that limits its focus to Java's Collections Framework containers. We've all run into problems with HashMaps, LinkedLists, HashSets and so on, so hopefully this tool helps us move beyond the painful primitiveness of having to use a plain debugger or profiler to tackle such bug scenarios. CollectionSpy features pretty impressive detection of hashing container corruption due to mutating keys, and the real-time animation of API accesses looks like nothing you've ever seen before in another profiler.
