With elastic/apm-server#7305 being resolved, I don't think this issue is blocked. @stuartnelson3 or @simitt, can you confirm that?

What's the best way to test this end-to-end once the UI component is enabled? Can someone from the UI or Server team do some basic testing with the Java agent team doing more extensive testing?

[simitt]

Agree, I am not aware of anything blocking from the apm-server side at this point.

What's the best way to test this end-to-end once the UI component is enabled? Can someone from the UI or Server team do some basic testing with the Java agent team doing more extensive testing?

How about creating a gh issue describing all the test cases and how to verify if everything works as expected. We can then derive automated tests and docs from this?

[felixbarny]

We have some test case definitions here: elastic/apm-agent-java#2196 (comment)

But also, would you recommend testing this on staging cloud or with apm-integration-testing? What are the steps to get a stack up and running?
