Note: FAIL means: "test threw exception", ERR means "deep equals test of serialized vs deserialized object returned false (either type changes or real error)".
The class structures tested are cycle free and reference sharing was turned off. In addition simple types where choosen in order to avoid test failures. Note that json.io and fst-json are capable to serialize much more complex object graphs (incl. ref restoring) compared to the simpler json serializers. fast-serialization's (fst) json encoder can serialize practically any serializable java object graph even supporting externalizable and custom serializers.

Test Class: FrequentPrimitives[]

A array[10] of objects with a typical distribution of primitve fields: 2 short Strings, 3 boolean, 6 ints, 2 long, one double.
