Did you find cases where cp-tools and javah are not usable? Please file
a bugreport then so that I could fix that.
Your note about jikes seems vague. I do not understand what you meant
by that.

I think you have not even looked at java-alt-setup.
It's just a script that invokes update-alternatives for all java-related
alternatives I know may exist. There's no "secondary" alternatives
system in free-java-sdk. This is only a helper I found useful myself.

Are you speaking from experience? In what way the free-java-sdk did not
work for you when building a package that build-depended on it? Under
what circumstances have you tested it?
I have not heard of any problems and got no bugreports from you.
OTOH I know that free-java-sdk does work for many people.

PS: A new version of free-java-sdk should be in the unstable tomorrow.
