Extension Instrumentation Class not found

[anuragagarwal561994]

Hello I have been trying to additional instrumentation using the extension API but in my Advice method I am not able to use any Singletons.

I tried different mechanisms and I always get class not found in AppLoader

Perhaps you forgot to implemented isHelperClass in your instrumentation module https://github.com/open-telemetry/opentelemetry-java-instrumentation/blob/main/docs/contributing/writing-instrumentation-module.md#tell-the-agent-which-classes-are-a-part-of-the-instrumentation-by-overriding-the-ishelperclass-method
