Actually I don't know exactly what IDEs do, like for example IntelliJ. They could also follow other strategies, like react on active/deactive of window, or react on terminate of a ant job or build job, etc.. Sometimes, if there are too many changes, I already notices that some of them might not be recognized. I also don't know whether a watcher can report content change. Ok I see OVERFLOW, events may have been lost, and ENTRY_MODIFY(*), entry in the directory has been modified. Oki Doki, everything is there, but because of OVERLOW(*) I guess a tool needs a fallback strategy. Thanks, interesting!
