If the DND operation is in progress, the IME API is invoked via SendMessage() call inside InvokeInputMethodFunction() to avoid a hang. The flag isInDoDragDropLoop indicates whether the DND takes place or not. The flag works properly if the DND is performed between two Java windows. However if anything is dragged from native app, (e.g. Windows FileExplorer) to Java the flag is NOT set. That’s the root cause of the hang.
