Bug 183732 [DataBinding] swallowing the exception in get/set value of the JavaBeanObservableValue
During the bidning of beans that have PropertyChangeSupport implemented but not properly initialized (i.e null), data binding "swallows" the NullPointerException only logging "Could not attach listener to".
bundles/org.eclipse.core.databinding.beans/src/org/eclipse/core/internal/databinding/internal/beans/JavaBeanObservableValue.java
Policy.JFACE_DATABINDING,
										IStatus.OK,
										"Could not change value of " + object + "." + propertyDescriptor.getName(), e)); 
			}
		} finally {
			updating = false;
		}
	}
	public Object doGetValue() {
		try {
			Method readMethod = propertyDescriptor.getReadMethod();
			if (readMethod == null) {
				throw new BindingException(propertyDescriptor.getName()
						+ " property does not have a read method."); 
			}
			if (!readMethod.isAccessible()) {
				readMethod.setAccessible(true);
			}
			return readMethod.invoke(object, null);
		} catch (Exception e) {
			if (BeansObservables.DEBUG) {
				Policy
						.getLog()
						.log(
								new Status(
										IStatus.WARNING,
										Policy.JFACE_DATABINDING,
