Description
Currently XStream has a number of built-in immutable types, including the Java Primitives and java.lang.String. XStream does not consider java.util.UUID to be immutable by default.
The single biggest functional difference between Immutable types and mutable ones, to XStream, is the use of XPath's to ensure reference equality once deserialized. This means that XStream maintains reference equality on UUID's. performing a reference-equals on UUID's is just as taboo as performing a reference-equals on two strings.
Therefore UUID should be added to the list of default Immutable types.
