Java RPMs should allow for side-by-side installation of JDK and JRE 32 and 64 bit and only one update for each major version
(Doc ID 2338304.1)
Last updated on DECEMBER 12, 2017
Applies to:Java SE JDK and JRE - Version 8 to 8
Information in this document applies to any platform.
There is a property in the RPM package, lets call it name, that determines whether, when you apply a new patch, the patch overwrites an existing package or whether it installs side-by-side.
Before Java 8U, all Java RPM packages were called Java SE (Or JDK or something like that; the important thing is that ALL had the same name).
They all can live together side by side happily.
If you get JDK 8u141 64 bit as the latest, it would overwrite JDK 8u101 64 bit (previous 8U 64-bit install) but leave the other ones alone.
This should be the way for the Jan'2018 CPU on wards.
