UUID.java - The actual implementation source.
UUIDTest.java - The test case for the UUID class. I've run this against the Sun 5.0_6 RI and it passes all tests.
UUID.ser - This is the serialized data from the RI implementation and is used by the UUIDTest. The full path under test/resources is "serialization/java/util".
The implementation is missing one thing at the moment, localized messages for the exceptions. I can add these and update the attachments, or I can add these as a second issue. Let me know.
