Hi Matthias,

the change looks good! I can sponsor it once we get the approval. Also forwarded to buil-dev for the minimal build change. Thank you and best regards, Volker

I'm getting an unsatisfied link error when using logstash on AIX but I suspect the issue is with AIX or the JRE, the exception is:

java.lang.UnsatisfiedLinkError: sun.management.OperatingSystemImpl.getProcessCpuLoad()D getProcessCpuLoad at sun/management/OperatingSystemImpl.java:-2 at org/logstash/instrument/monitors/ProcessMonitor.java:40 detect at org/logstash/instrument/monitors/ProcessMonitor.java:79 generate at org/logstash/instrument/reports/ProcessReport.java:15 this is the line in logstash: this.cpuProcessPercent = scaleLoadToPercent(unixOsBean.getProcessCpuLoad()); https://github.com/elastic/logstash/blob/master/logstash-core/src/main/java/org/logstash/instrument/monitors/ProcessMonitor.java

Could anybody help steer me in the right direction? This fix addresses the missing getSystemCpuLoad and getProcessCpuLoad on AIX . JDK8 is only affected , JDK9 and higher is not affected . Could I get a review for this change ? Change : http://cr.openjdk.java.net/~mbaesken/webrevs/8193807/ Bug : https://bugs.openjdk.java.net/browse/JDK-8193807 Thanks, Matthias
