FULL PRODUCT VERSION :
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows [Version 10.0.14393]

EXTRA RELEVANT SYSTEM CONFIGURATION :
Same on OpenSUSE Leap 42

A DESCRIPTION OF THE PROBLEM :
javafx.beans.property
Class MapPropertyBase<K,V>

public void addListener(ChangeListener<? super ObservableMap<K,V>> listener)

If 2 or more listeners are added via this API nothing happens on any map change. Only single listener works properly.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the provided source code.

If 2 listeners for "map" are commented then remaining single listener works.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Map Listener 1
Map Listener 2
Map Listener 3
Boolean Listener 1
Boolean Listener 2
Boolean Listener 3
ACTUAL -
Boolean Listener 1
Boolean Listener 2
Boolean Listener 3

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
package observabletest;

import javafx.beans.property.SimpleBooleanProperty;
import javafx.beans.property.SimpleMapProperty;
import javafx.collections.FXCollections;

public class ObservableTest {
    public static void main(String[] args) {
        SimpleMapProperty<String, String> map = new SimpleMapProperty<>(FXCollections.observableHashMap());
        SimpleBooleanProperty b = new SimpleBooleanProperty(false);

        map.addListener((x,y,z) -> System.out.println("Map Listener 1"));
        map.addListener((x,y,z) -> System.out.println("Map Listener 2"));
        map.addListener((x,y,z) -> System.out.println("Map Listener 3"));

        b.addListener((x,y,z) -> System.out.println("Boolean Listener 1"));
        b.addListener((x,y,z) -> System.out.println("Boolean Listener 2"));
        b.addListener((x,y,z) -> System.out.println("Boolean Listener 3"));

        map.put("1", "2");
        b.set(true);
    }
}
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Use another ObservableMap instance, bind to this one and add a single listener to each one. Both listeners work. It seems like any number of bindings works as long as only one listener is added per ObservableMap instance.
