I converted two machines from icedtea (java6) to oracle-jdk-bin
(java7).
I did in effect
emerge --depclean icedtea icedtea-web =virtual/jdk-1.6.0 =virtual/jdk-1.6.0
On one machine portage now claims that I basically don't need java (see
the output of --depclean below). Can this be right? More importantly,
I believe it is safe to do the suggested unmerges (i.e. I could always
remerge them) since
1. None of these are in system
2. Portage itself doesn't use java
Am I correct that letting the unmerge happen is reversible.
thanks,
allan

* Depclean may break link level dependencies. Thus, it is
* recommended to use a tool such as `revdep-rebuild` (from
* app-portage/gentoolkit) in order to detect such breakage.
*
* Always study the list of packages to be cleaned for any obvious
* mistakes. Packages that are part of the world set will always
* be kept. They can be manually added to this set with
* `emerge --noreplace <atom>`. Packages that are listed in
* package.provided (see portage(5)) will be removed by
* depclean, even if they are part of the world set.
*
* As a safety measure, depclean will not remove any packages
* unless *all* required dependencies have been resolved. As a
* consequence, it is often necessary to run `emerge --update
* --newuse --deep @world` prior to depclean.
Calculating dependencies... done!
