Error during deserialization when an object contains a reference to itself in JBoss EAP 6

Issue

• When deserializing certain object structures, a NullPointerException is caused by a call to a non-initialized object's equals() method.
• When an object contains a reference to itself (nested arbitrarily deep), any access to the nested reference during deserialization can access a non-initialized object (fields not set).
• On EAP 6.0.1, the deserialization of objects containing Map/Set fails in certain conditions.
