sun.awt.util.ThreadGroupUtils, java.io.IOException, java.util.Set, .WeakHashMap, javax.imageio.stream.ImageInputStream
This class provide means to properly close hanging image input/output streams on VM shutdown. This might be useful for proper cleanup such as removal of temporary files. Addition of stream do not prevent it from being garbage collected if no other references to it exists. Stream can be closed explicitly without removal from StreamCloser queue. Explicit removal from the queue only helps to save some memory.
