Hi Volker and Götz,

thank you for all the work you have done regarding the PowerPC/AIX Port!
The job was often tough, but you never gave up. It was a great achievement which I’d like to emphasize again.

I appreciate the nomination as new lead and I’ll be glad to accept. I’m looking forward to continue the collaboration with IBM/RedHat and Oracle.

Best regards,

Volker, many thanks for initiating and driving the ppc/aix
port up to now!

And yes, SAP proposes Martin Doerr[1] as new lead of the
PowerPC/AIX Port Project [2][3][4].

In the future, SAP will concentrate on supporting
linuxppc64le (little endian) in jdk/jdk, jdk17 and jdk11. I.e., SAP
will assure best quality by continuously building and testing these
repositories.  IBM will take the responsibility of the AIX port.

The linuxppc64 (big endian) port will be discontinued [5] as it
is nowadays superseded by the little endian port. SAP will also
terminate its testing efforts of the ppc platforms in OpenJDK 8u [6].
IBM will continue the support of linuxppc64 (le, be) in 8 and 11.

Naturally, SAP will always respond to issues raised against the
linuxppc64, linuxppc64le or aixppc64 ports in any jdk version
with appropriate effort.

Best regards,
Goetz and Tim

[5] The last releases where SAP tests linuxppc64 will be 11.0.12 and 17.
[6] The last release of 8 where SAP tests linuxppc64 and aix will be
    the July 2021 security update.
