Unfortunately I lost the thread that this email really responds to...

As previously noted, it is possible, though not particularly easy, to 
decompile bytecode to source.

My understanding is that when the architecture neutral distribution format 
(ANDF) people at OSF developed the ANDF spec, they spent a lot of time 
ensuring that it was "not possible" to decompile ANDF code to source.  They 
were extremely concerned about intellectual property issues associated with 
giving people mechanisms that permitted access to source.  They believed 
that if it were not possible to protect source, it would be significantly 
more difficult to get vendors to sign up to deliver their code in ANDF.  (Of 
course ANDF never went anywhere, but that is/may be a different issue...)

It seems to me that it would not be a good idea to ignor the ANDF work on 
source access as JAVA goes forward, otherwise it might limit the potential 
for the future.
