      On the client side, during deserialization of an object graph, if one of the object's class doesn't have a no-arg constructor, the deserialization runs into a NullPointerException which looks like:

      java.lang.NullPointerException
	at org.jboss.marshalling.reflect.SerializableClass.invokeConstructorNoException(SerializableClass.java:510)
	at org.jboss.marshalling.reflect.SerializableClass.callNonInitConstructor(SerializableClass.java:484)

	at org.jboss.marshalling.AbstractObjectInput.readObject(AbstractObjectInput.java:41)

      The class within the object graph that triggered this, in this specific case was org.glassfish.json.JsonLocationImpl whose source is here https://java.net/projects/jsonp/sources/git/content/impl/src/main/java/org/glassfish/json/JsonLocationImpl.java
