研究方向
Investigate the trace entry causing the NullPointerException in ReflectionProcessor.processEntry. Look at the Nacos client code in the CredentialWatcher class to understand the getSystemResource call. Consider if the issue is in GraalVM agent or Nacos client. A potential fix could be to add null checks in the tracing code or adjust the reflection configuration.
