Packages:

  developer/java/jdk
  library/java/java-demo
  runtime/java/jre

allow customers to install the jdk, jre, or java-demos and have the system automatically update them to the latest version of Java available as new versions are released.


We did it in java6:
https://bugs.openjdk.java.net/browse/JDK-8023053 (IPS java convenience packages should not be marked obsolete)
We left runtime/java as not obsoleted package in 6
but unfortunately in 6 there was runtime/java but in 7 there is runtime/java/jre
so we ran into
https://bugs.openjdk.java.net/browse/JDK-8069029(Pkg update problems with obsoletion of JDK 6.)
https://bug.oraclecorp.com/pls/bug/webbug_print.show?c_rptno=20283334
Finally we also obsoleted runtime/java in 6

Java7 and Java8 both have runtime/java/jre
so this package should not be marked obsolete in 7.
