I'm using Gson to generate debug ouput in my application

Gson gson = new GsonBuilder().setPrettyPrinting().serializeNulls().create();
gson.toJson(myObject);

But Gson does complain about a circular reference error when attempting to serialize a data structure. Can this be done with Jackson library?

UPD Gson 2.3.1: Released Nov 20, 2014

Added support to serialize objects with self-referential fields. The self-referential field is set to null in JSON. Previous version of Gson threw a StackOverflowException on encountering any self-referential fields.
    The most visible impact of this is that Gson can now serialize Throwable (Exception and Error)
java jackson gson
