I'm trying to debug coroutines using a javaagent form the kotlinx-coroutines-debug library. After sending a SIGTRAP signal there are coroutines stacktraces like following:

Coroutine StandaloneCoroutine{Active}@4491c16c, state: SUSPENDED
        ...

Coroutine StandaloneCoroutine{Active}@27559007, state: SUSPENDED
        ...

However it is not possible to understand which stack belongs to which coroutine. All my coroutines have unique names. Is it possible to activate printing of coroutine names?

[Alexander]

There is an example of such a coroutine stacktrace on https://github.com/Kotlin/kotlinx.coroutines/blob/master/kotlinx-coroutines-debug/README.md:

Coroutine "coroutine#2":DeferredCoroutine{Active}@289d1c02, state: SUSPENDED

So I'm wondering is it a regression or there is a possibility to activate the feature.

According to the sources, that string contains just the result of toString() of the continuation, which doesn't contain the name of the coroutine.

Yeah. I've found it. And there is also a bug in tests. I'm trying to fix it and possibly will make a PR

By the way, I recommend the library for fixing exception stack traces in coroutine code.

toString() method of a coroutine contains its name if following property is set:

-Dkotlinx.coroutines.debug=on
