Description of problem:
After upgrade (say 5.6.0 -> 5.8.0) we upgrade java and keep he old java there. It might be a good idea to advise customers to remove old packages if they do not need them for any reason on the satellite.
For example when upgrading from 5.6 to 5.8 you can remove old java packages using
yum remove java-1.6.0-ibm java-1.7.1-ibm
