JavaBeanObjectPropertys are not gargabe collected, continuously producing them results in a OutOfMemoryException.

This minimal setup produces the exception:

===============

import java.beans.PropertyChangeListener;
import java.beans.PropertyChangeSupport;

import javafx.beans.property.adapter.JavaBeanObjectProperty;
import javafx.beans.property.adapter.JavaBeanObjectPropertyBuilder;

import org.junit.Test;

public class MemoryLeakTest {

public class FaceBean {
private int mouthWidth = 90;
private final PropertyChangeSupport mPcs = new PropertyChangeSupport(this);

public int getMouthWidth() {
return mouthWidth;
}

public void setMouthWidth(final int mw) {
int oldMouthWidth = mouthWidth;
mouthWidth = mw;
mPcs.firePropertyChange("mouthWidth", oldMouthWidth, mw);
}

public void addPropertyChangeListener(final PropertyChangeListener listener) {
mPcs.addPropertyChangeListener(listener);
}

public void removePropertyChangeListener(final PropertyChangeListener listener) {
mPcs.removePropertyChangeListener(listener);
}
}

@Test
@SuppressWarnings({ "unchecked" })
public void produceMemoryLeak() throws NoSuchMethodException {

while (true) {
FaceBean faceBean = new FaceBean();
JavaBeanObjectPropertyBuilder<?> builder = new JavaBeanObjectPropertyBuilder<>();
JavaBeanObjectProperty<Integer> mouthWidthProperty = builder.bean(faceBean).name("mouthWidth").build();

mouthWidthProperty.dispose();
mouthWidthProperty.unbind();
}
}
}

===============


The problem is in the JavaBeanObjectProperty's constructor. Removing the following part resolves the OutOfMemoryException.

===============
Cleaner.create(this, new Runnable() {
            @Override
            public void run() {
                JavaBeanObjectProperty.this.descriptor.removeListener(listener);
            }
        });
===============

Inspecting the heap shows that the cleaner never gets collected, holding a reference to the JavaBeanObjectProperty, which ultimately holds a reference to the value object, so it won't be collected either.
