• ok, missing dependency

@sysmat are you sure that was an actual exception or just a debug log of Sentry?

We've already noticed that the debug logs are not ideal so we're going to remove those log lines in #4091

[sysmat]

@adinauer it was in junit5 test, stack error was in console as DEBUG.

DEBUG: Class not available:io.sentry.opentelemetry.agent.AgentlessSpringMarker

[adinauer]

Yeah sorry about that, we're gonna remove those from the logs in the next release. There's up to three of them (AgentMarker, AgentlessMarker and AgentlessSpringMarker).

It seems like in 8.1.0 I am still getting getting this DEBUG log, but different class missing:

DEBUG: Class not available:io.sentry.opentelemetry.OtelContextScopesStorage
java.lang.ClassNotFoundException: io.sentry.opentelemetry.OtelContextScopesStorage

[adinauer]

Thanks for the report @kle-pra seems like I forgot some locations where this is also happening. We'll fix it.

[adinauer]

You can safely ignore this. I've opened a PR to fix it. We'll include it in the next release.
