resolves #1270

[breedx-splk]

Hey @sethAmazon thanks for the PR. I don't see anything immediately concerning/problematic with it, however I would like to confirm that this really is the case. Can you help to explain maybe how spring boot enters into this? I'm unclear about that.

I downloaded and ran tomcat 10.1.19 and the management bean was still named Catalina. Is the app you were testing with available as a repro somewhere?

@breedx-splk Also see open-telemetry/opentelemetry-java-instrumentation#10115

[breedx-splk]

Ok, given the similar changes in instrumentation, this seems like a good improvement. Thanks again.
