Description of problem:
If one sets an alternative for something to the _last_ available item
and then uninstall the package offering that alternative, then that
something is not changed to the best available alternative as expected,
leaving dangling symlinks and an unusable program(s).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. remove all installed java-devel packages
1. yum install java-1.4.2-gcj-compat-devel
2. yum install java-1.6.0-openjdk-devel
3. alternatives --config javac, select the _last_ item
(should be /usr/lib/jvm/java-1.6.0-openjdk*/bin/javac)
4. alternatives --display javac | head -n2
(status manual, link points to /usr/lib/jvm/java-1.6.0-openjdk*/bin/javac)
5. yum remove java-1.6.0-openjdk-devel
6. alternatives --display javac | head -n2
(status manual, link points to /usr/lib/jvm/java-1.6.0-openjdk*/bin/javac--wrong!)
Symlinks are restored to point to the best available alternative.
Source code looks the same in Fedora Rawhide version, so I presume the
same bug is present there (I haven't checked it).

I created a RHTS test for this bug (/CoreOS/chkconfig/Regression/bz525051-alternatives-can-leave-dangling-symlinks-after). The test passed on architectures that provide the package java-1.6.0-openjdk-devel. These are i386 (server, client), x86_64 (server, client). On architectures s390x, ppc64 and ia64 currently only java 1.4 is provided. I consider this chkconfig test as successful.
