      Description

      Run the following example app:

      import javafx.application.Application;
      import javafx.event.ActionEvent;
      import javafx.event.EventHandler;
      import javafx.scene.Node;
      import javafx.scene.Scene;
      import javafx.scene.control.ButtonType;
      import javafx.scene.control.Dialog;
      import javafx.scene.control.Menu;
      import javafx.scene.control.MenuBar;
      import javafx.scene.control.MenuItem;
      import javafx.scene.control.TextArea;
      import javafx.scene.input.KeyCombination;
      import javafx.scene.layout.Priority;
      import javafx.scene.layout.VBox;
      import javafx.stage.Stage;

      public class DialogConcurrentModification extends Application {

      private class MyDialog extends Dialog<Void> {

      public MyDialog() {
      setTitle("Test");
      getDialogPane().setContent(createPresentation());
      getDialogPane().getButtonTypes().addAll(ButtonType.CLOSE);
      }

      private TextArea output = new TextArea() {
      public void copy() {
      super.copy();
      close();
      };
      };

      private Node createPresentation() {
      VBox vbox = new VBox();
      output.setText("Test 123");
      output.setEditable(false);
      output.prefWidthProperty().bind(vbox.widthProperty());
      output.setPrefHeight(300);
      output.selectAll();
      VBox.setVgrow(output, Priority.ALWAYS);
      vbox.getChildren().addAll(output);
      return vbox;
      }
      }

      public DialogConcurrentModification() {
      }

      @Override
      public void start(Stage stage) throws Exception {
      stage.setTitle("DialogConcurrentModification");
      Scene scene = new Scene(new VBox(), 400, 350);

      MenuBar menuBar = new MenuBar();

      // --- Menu File
      Menu menuFile = new Menu("File");
      menuBar.getMenus().addAll(menuFile);

      MenuItem test = new MenuItem("Open Dialog");
      test.setAccelerator(KeyCombination.keyCombination("Ctrl+O"));
      test.setOnAction(new EventHandler<ActionEvent>() {
      public void handle(ActionEvent t) {
      Dialog<Void> dlg = new MyDialog();
      dlg.showAndWait();
      }
      });

      menuFile.getItems().add(test);

      ((VBox) scene.getRoot()).getChildren().addAll(menuBar);

      stage.setScene(scene);
      stage.show();
      }

      public static void main(String[] args) {
      launch(args);
      }
      }

      Open the dialog (Ctrl+O), then right-click into the textarea and select "copy" from the context-menu. This should copy the text into the clipboard and close the dialog.

      Under Windows (and only there) an Exception is thrown however:
