I have enabled JMX in my tomcat server. I use VisualVM to inspect the tomcat server.
When I look at java.lang->OperatingSystem I'm seeing a -1 value for a few CPU value readings. This just suddenly happened. I cant think what changes might have been made, I don't recall any apart from maybe a Windows Update [image: jmx.png] The java version is Eclipse Temurin JDK version 17.0.11 build 17 Can anyone explain this or advise on how to debug further? There was a report here about this issue. I tried going to JDK 18 but this did not help. https://bugs.openjdk.org/browse/JDK-8265104
