New Machine requirement - AIX 7.2TL05 for testing JDK22+

[sxa]

I need to request a new machine:

• New machine operating system (e.g. linux/windows/macos/solaris/aix): AIX 7.2TL05
• New machine architecture (e.g. x64/aarch32/arm32/ppc64/ppc64le/sparc): ppc64
• Provider (leave blank if it does not matter): OSUOSL
• Desired usage: Testing JDK22+ which requires support for OpenXL17 which is only available in a later TL of AIX
• Any unusual specification/setup required:
• How many of them are required: TBC

Please explain what this machine is needed for: Running tests against JDK22+ which is being built with OpenXL17

Follow on to https://github.com/adoptium/infrastructure/issues/3208

Three options discussed on the call today:

1. Provision new machines with a suitable level of AIX (Preferred option, and the one we will try first)
2. Upgrade some of the existing test machines to the new level and install the OpenXL17 runtime on them
3. If insufficient capacity is available for (1), decommission some of the existing test machines one at a time and use that capacity to provision replacements.

NOTE: Not directly related to getting JDK22+ built and tested but I performed a build of JDK17 using the xlc16 compiler on the new 7.2TL5 build machine and it did not run on the earlier TL that we have on the other machines:

Ref: https://ci.adoptium.net/job/build-scripts/job/jobs/job/jdk17u/job/jdk17u-aix-ppc64-temurin_SmokeTests/240/console Build was done at https://ci.adoptium.net/job/build-scripts/job/jobs/job/jdk17u/job/jdk17u-aix-ppc64-temurin/390/ 14:24:11 configure: Using xlc C compiler version 16.1.0 [IBM XL C/C++ for AIX, V16.1.0 (5725-C72, 5765-J12) Version: 16.01.0000.0011] so it is seems to be the case (as expected) that if we were to move older versions to build on a TL05 system then we would lose compatibility with earlier TLs that we currently run on, even if we're still using the older compiler.
