Issue/Introduction

AutoProbe.log shows multiple sections showing processing of class sun/net/www/protocol/http/HttpURLConnection

Does this indicate the class is loaded multiple times - maybe by separate class loaders? Could this give rise to any performance issues?

Environment

DX APM Agent

Resolution

Feedback from APM Engineering:

- yes, it's possible that same class loaded by different class loader.

- no, we won't instrument same class multiple times. we do have internal check to prevent that.
