RFR [jdk8] : 8193807 : AIX: avoid UnsatisfiedLinkError by providing empty basic implementations of getSystemCpuLoad and getProcessCpuLoad

[Volker Simonis]

Hi Martin,

I'm afraid that's not easy to answer. The fix didn't made it into
8u162 which will be released in January 2018 [1]. It is targeted for
8u172 but there is no time-line for 8u172 yet [2].

The best you can do is to ask on the 8u-dev [3] mailing list or ask
the people at AdoptOpenJDK (adoption-discuss at openjdk.java.net [4]) to
merge the fix into their current builds. That would be actually a good
smoke test for their tool chain :)

Regards,
Volker
