Supporting CLASSPATH for /etc/alternatives/java

[Daniel Bonniot <Daniel.Bonniot@inria.fr>]

The policy states that "I /should/ use /etc/alternatives for the name 
'java' if they are command-line compatible with the Sun's java program."

First, I suppose that "I" is a typo, and should read "They".

Second, should we specify that they should also treat the environment 
variables like Sun's java? Specifically, that they should honor the 
CLASSPATH variable?

At least sablevm is providing an alternative for "java", but does not 
seem to look at the CLASSPATH. I was thinking about reporting this as a 
bug, but it would make more sense to clarify that issue in the policy.

If we decide not to require jvms to honor CLASSPATH, I think we should 
say it explicitely in the policy, in a section about how to make a 
portable use of the java command.

PS: sablevm does not support -classpath either, but requires --classpath 
(double hyphen). I will bug report this, as it is a policy violation.
