[kaffe] Misc. serialization patches

[Mattias Rehnberg]

Hi,

Refering to the document at the URL below, 'classdata' will be writen on the form 'wrclass objectAnnotation' if it has a write method instead of just 'nowrclass'. Since objectAnnotation is a least an endBlockData byte, you'll get that byte when you try to deserialize the next object in the stream.

I found this when I tried to deserialize a stream of two Vectors written with Sun's Java, the first one deserialized ok, but the second one gave me a null reference.

http://java.sun.com/j2se/1.4.2/docs/guide/serialization/spec/protocol.html

Best Regards,
Mattias

Thanks. Just one question: I don't remember why we should call 
defaultWrite/ReadObject in Vector. The logic behind this call is the 
same as if there would not be any write/readObject. BTW, these two 
patches concerning the core java library have to go to 
classpath at gnu.org.   As they are two lined I don't think you'll need 
paperwork. ;)

Thanks,

Regards,

Guilhem.
