Immutability

Jersery 2.5 allows developers to bind incoming data to immutable fields (values defined using the final keyword). The only requirement is that the class have a default constructor.

Microserver encourages deep Immutability by integrating Google's Guava libraries which include Immutable collections. Microserver will configure Jackson the JSON / XML processor configured to be used by Jersey to automatically serialise and deserialise Guava Immutable collections.
