JFileChooser.getSelectedFiles() failed to retrieve files with multi-selection and double-click. This occurs when a single file is selected then enable multi-selection then select the same file through mouse double-click(Two file chooser dialogs used before and after multi-selection enabled). SelectedFiles are updated when a change in files/directory selection is done or when selection is made through keyboard selection. In this case since a single file is selected before multi-selection is enabled and same file is selected again without changing the selection index/directory, leaving selected Files un-updated. **Proposed Fix** : Whenever Multi-Selection is enabled check if any files are selected, if yes update the selected Files of JFileChoooser.
