SystemCpuLoad return -1 with Eclipse Adoptium 21.0.5 on AIX 7.2 ppc64 system

Hi there, I am experiencing an issue where the SystemCpuLoad attribute from the MBean object java.lang:type=OperatingSystem consistently returns -1 on an AIX 7.2 ppc64 system with Temurin JDK 21.0.5.

To reproduce, I used a sample Java class, which retrieves CPU load information by invoking java.lang.management.ManagementFactory.getPlatformMBeanServer(). When running the script on AIX, the returned CPU load is always -1. For comparison, I tested the same script using IBM Semeru JDK 21.0.5, where the system CPU load outputs a valid result. Could you please advise any guidance or steps to address this issue? Thank you!

Temurin JDK 21
> System CPU Load: -1.0

IBM Semeru JDK 21
> System CPU Load: 0.01841305215837936
