context is not used anywhere within this method; the span started in the OnMethodEnter advice does not seem to be ended. Is that correct? Is this span needed?

span is needed for initializing the ServletContextPath. I have updated the code to end advice.

You shouldn't need to create a span to use ServletContextPath. The ServletContextPath is supposed to be initialized somewhere in the application server layer, in a different instrumentation; here you're just reading whatever value was set before.

@mateuszrzeszutek after some further investigation, http.route is correct when otel.instrumentation.common.experimental.controller-telemetry.enabled is false with my change and http.route is incorrect when controllerTelemetryEnabled is true.
