      Description

      It is impossible to catch an unexpected RuntimeException from an ActionEvent in a generic way.
      A customized response to that exceptions is impossible, which is critical for us because our application is a 24/7 app for a power plant control system.

      Here is a sample app:
      ============================================
      import java.lang.Thread.UncaughtExceptionHandler;
      import javafx.animation.PauseTransition;
      import javafx.application.Application;
      import javafx.beans.property.IntegerProperty;
      import javafx.beans.property.SimpleIntegerProperty;
      import javafx.stage.Stage;
      import javafx.util.Duration;

      public class ListenerExceptionTest extends Application {

      @Override
      public void start(Stage stage) throws Exception {

      Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler() {
      @Override
      public void uncaughtException(Thread t, Throwable e) {
      System.out.println("Caught in DefaultUncaughtExceptionHandler: " + t + " " + e);
      }
      });

      IntegerProperty counter = new SimpleIntegerProperty(0);

      counter.addListener(o -> {
      throw new RuntimeException("Unexpected RuntimeException in InvalidationListener");
      });

      PauseTransition counterIncrement = new PauseTransition(Duration.seconds(1));
      try {
      counterIncrement.setOnFinished(e -> {
      counter.set(counter.get() + 1);
      counterIncrement.playFromStart();
      throw new RuntimeException("Unexpected RuntimeException in ActionEvent");
      });
      } catch (Exception e) {
      System.out.println("Caught from setOnFinished: " + e);
      }
      counterIncrement.playFromStart();

      stage.show();
      }

      public static void main(String[] args) {
      try {
      launch(args);
      } catch (Exception e) {
      System.out.println("Caught in main: " + e);
      }
      }

      }
      ============================================

      It results in:
      ============================================
