Spring Actuator created extra resources in APM

Compare tracing behavior between versions 1.53.0 and 1.55.0 for Spring Actuator requests, using the OperationHandler.handle entry point and the supplied DD_TRACE_DEBUG trace as the starting evidence. Reproduce the Kubernetes health-check request and verify that excluded actuator resources no longer create extra APM resources.

Tracer Version(s)

1.54.0, 1.55.0

Java Version(s)

25.0.36

Bug Report

After updating from 1.40.1 to 1.55.0, I noticed a lot of requests for a Resource named OperationHandler.handle inside APM on a Service. I eventually linked it to Spring Actuator requests, mostly from a Kubernetes health check.
We have ".*/actuator.*" set to be excluded at the Datadog Agent level in the cluster, but there seemed to be a new span created for each actuator call.

I gradually reverted the library version and once I got to 1.53.0, the issue went away.

Here's a bit of an excerpt for a single Trace from the logs with DD_TRACE_DEBUG=true:
