[kaffe] Serialization

[Guilhem Lavaux]

Hi,

Finally, I have followed kaffe's regression tests. Classpath's 
serialization passes all kaffe's tests, although one is wrong
according to JDK 1.4.2 (TestSerialVersions.Test0007 should give "null, 
105"). serialPersistentFields is now also used
by the reading process to create some more fields to ensure 
compatibility. For the moment I do know how to deal with
the last failing test (I do not even know if it is not a bug in the JDK, 
the behaviour is really weird).

Cheers,
Guilhem.

P.S.: I will send to Mark the last patch against Classpath and will soon 
commit the code in kaffe's CVS.
