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



    • Resolved In Build:
    • Verification:



        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 wether it installs “side-by-side”:

        Before 8uSomething all Java RPM packages were called “Java SE” (Or “JDK" or something like that.. the important thing is that ALL had the same name).


            JRE 7u80 32 bit -> “Java SE”
            JDK 8u101 64 bit -> “Java SE”
            JRE 7u95 64 bit -> “Java SE”

        So if you tried to use “yum update” you could only have 1 flavor. If you needed say “the latest 7 AND the latest 8” you couldn’t use “yum update” for one since it would overwrite all others. You could always use the tar.gz and do whatever you wanted but you couldn’t use yum.

        With 8uSomething, requested that we allow “side by side”.

        We changed then to have the packages include the version number so:

        JRE 8u101 -> “Java SE 8u101”
        JRE 8u131 -> “Java SE 8u131”

        Not sure if the change also went to 7 and 6 but that was done for 8 at least.

        Now you could have “side by side” of 7 and 8.. but also if you “updated” from 8u101 with 8u131 you would not “overwrite” 8u101 but keep 8u101 AND 8u131.

        We also used “Java SE <version>” for both JDK and JRE, 32 and 64 bit so you can’t use “YUM install” for 8u131 32 bit AND 8u131 64 bit as they would overwrite each other.

          Allow “side-by-side” of different packages (JDK vs JRE), different bitness (32 vs 64) and different major/feature versions (e.g. 7, 8, and 9) but within a “major/feature - package - bitness” combination one should overwrite.

        Have the “names” be “<JDK|JRE> <Major> <Bitness>”

        In our previous examples:

        JRE 7u80 32 bit -> “JRE 7 32 bit”
        JDK 8u101 64 bit -> “JDK 8 64 bit
        JRE 7u95 64 bit -> “JRE 7 64 bit”

        They can all live together side by side happily.

        If you go and get JDK 8u141 64 bit it would also be “JDK 8 64 bit” so it would overwrite JDK 8u101 64 bit but leave the other ones alone.

        That was the primary request. JDK-8189805 completed this, for 9,8,7, and 6

        Secondary request:

        Since you might have JRE 7, 8, and 9 in the same machine use the “alternative” mechanism (I dont’ understand this completely but seems like you can create some symlinks to assign the “default” version) for choosing which version you use if you don’t call out exactly one.

        That request WAS NOT completed by JDK-8189805 . This was a “good to have” so its not a deal breaker.
