```
public final class OpenTelemetrySdkAccess
extends Object
```
A helper to facilitate accessing OpenTelemetry SDK methods from instrumentation. Because instrumentation runs in the app classloader, they do not have access to our SDK in the agent classloader. So we use this class in the bootstrap classloader to bridge between the two - the agent classloader will register implementations of needed SDK functions that can be called from instrumentation.
