While debuging a swing application I saw this thread appears quite offen. There is a another thred call "Image Fetcher 1" also.

can someone please explaint to me what does this thread do. Is it realted to "SwingWorker" Thread.

Answer 1

When you attempt to load a media resource in Swing, the request is passed to an instance of MediaTracker. The MediaTracker implementation will then allocate the loading task to one of a pool of image fetcher threads.
