Public bug reported:

I have a headless automated-build server. The server executes a script
which depends on Apache Ant. The "ant" package depends on "openjdk-6
-jre-headless" which invokes "update-alternatives" as part of the
installation process clobbering my existing Oracle JDK installation.

This is an automated build server. I cannot be expected to manually
restore "update-alternatives" every time someone needs a new dependency.
As such, I expect the build script not to clobber the symbolic links in
the first place.

Please avoid invoking "update-alternatives" if /usr/bin/java or
/etc/alternatives/java are already set. When a user installs "openjdk-6
-jre-headless" it does not necessarily mean they want it to replace the
default JDK. It's one thing to set yourself as the default if no JDK
exists, it's another thing to clobber existing values. If the user wants
to change the default, they can always do so after the installation
concludes. The contrary (restoring the default JDK) is not necessarily
true.

In my case, the build machine has sudo access to "apt-get" but not to
"update-alternatives" because it is not meant to touch system defaults.
As such, it has no way of restoring the default JDK if it gets
clobbered.

Alternatively, please provide a mechanism for installing "openjdk-6-jre-
headless" without running "update-alternatives" in a way that will allow
me to run "apt-get install ant" at a later time without it asking to
install "openjdk-6-jre-headless" a second time.

Final point: if you disagree, please do not close this issue
immediately. Present your points and give me an opportunity to respond.

Thank you.
