Java library to serialize objects to XML and back again

The features of the XStream library are:

 - Ease of use. A high level facade is supplied that simplifies common
   use cases.
 - No mappings required. Most objects can be serialized without need
   for specifying mappings.
 - Performance. Speed and low memory footprint are a crucial part of
   the design, making it suitable for large object graphs or systems
   with high message throughput.
 - Clean XML. No information is duplicated that can be obtained via
   reflection. This results in XML that is easier to read for humans
   and more compact than native Java serialization.
 - Requires no modifications to objects. Serializes internal fields,
   including private and final. Supports non-public and inner classes.
   Classes are not required to have default constructor.
 - Full object graph support. Duplicate references encountered in the
   object-model will be maintained. Supports circular references.
 - Integrates with other XML APIs. By implementing an interface,
   XStream can serialize directly to/from any tree structure (not just
   XML).
 - Customizable conversion strategies. Strategies can be registered
   allowing customization of how particular types are represented as
   XML.
 - Error messages. When an exception occurs due to malformed XML,
   detailed diagnostics are provided to help isolate and fix the
   problem.
 - Alternative output format. The modular design allows other output
   formats. XStream ships currently with JSON support and morphing.
