研究方向
The issue involves a JVM crash when using JMX getSystemCpuLoad with Sentinel. The attached hs err log file (hs err pid6440.log) should be analyzed to identify the crash location and potential causes. Reproduce the issue with a minimal Sentinel setup and JMX monitoring, and check for known JVM bugs or Sentinel configuration issues. Look at related issues and pull requests in the Sentinel repository for context.
