    Description

      Since I first tested JavaFX 8 (b83) I can't really use my application, due to a StackOverflowError, which is caused by CSS. Now I tested with b101 and it still exists.

      Appearently it only occurs with Modena style.

      Here's how you can reproduce it (use the menu or select the table row):


          import javafx.application.Application;
          import javafx.beans.property.SimpleStringProperty;
          import javafx.beans.value.ObservableValue;
          import javafx.collections.FXCollections;
          import javafx.scene.Scene;
          import javafx.scene.control.*;
          import javafx.scene.layout.VBox;
          import javafx.stage.Stage;
          import javafx.util.Callback;
          public class TestApp extends Application {
              public static void main(String[] args) {
                  launch();
              }
              @Override
              public void start(Stage stage) throws Exception {
                  MenuBar menuBar = new MenuBar();
                  Menu menu = new Menu("Menu");
                  menu.getItems().add(new MenuItem("test"));
                  menuBar.getMenus().add(menu);
                  TableView<String> tableView = new TableView<String>();
                  tableView.setItems(FXCollections.observableArrayList("String"));
                  TableColumn<String, String> tableColumn = new TableColumn<String, String>();
                  tableColumn.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<String, String>, ObservableValue<String>>() {
                      @Override
                      public ObservableValue<String> call(TableColumn.CellDataFeatures<String, String> stringStringCellDataFeatures) {
                          return new SimpleStringProperty(stringStringCellDataFeatures.getValue());
                      }
                  });
                  tableView.getColumns().add(tableColumn);
                  VBox vBox = new VBox();
                  vBox.getChildren().add(menuBar);
                  vBox.getChildren().add(tableView);
                  Scene scene = new Scene(vBox);
                  scene.getStylesheets().add("/styles.css");
                  stage.setScene(scene);
                  stage.show();
              }
          }


      styles.css:

      .root {
              -fx-selection-bar: linear-gradient(to bottom, derive(-fx-background, -7%) 0%, derive(-fx-background, -34%) 100%);
          }



      The error is:

          java.lang.StackOverflowError
              at com.sun.javafx.css.SimpleSelector.applies(SimpleSelector.java:236)
              at com.sun.javafx.css.CompoundSelector.stateMatches(CompoundSelector.java:233)
              at com.sun.javafx.css.CompoundSelector.stateMatches(CompoundSelector.java:206)
              at javafx.scene.CssStyleHelper.getStyle(CssStyleHelper.java:702)
              at javafx.scene.CssStyleHelper.resolveRef(CssStyleHelper.java:951)
              at javafx.scene.CssStyleHelper.resolveLookups(CssStyleHelper.java:1022)


      I believe the error is, that it can't resolve -fx-background.
