Hi there,

I'm an intern over at IBM and I'm trying to build the Java SDK. When I run the gradle build, I get a rather lengthy stack trace at this point. I've run the stack trace through google but, other than a closed ticket from 2021 and one from 2020, I haven't had any results, and there were no related discussions that I could find.

ChatGPT suggested that it's due to a race condition but I am only so confident in its ability to actually describe the issue meaningfully.

The build is successful, so I'm wondering if this is just a stack trace that I can consider "within acceptable paramaters"

I've attached the buildOutput if it's helpful but the stack trace looks like this:

    [Test worker] ERROR io.grpc.internal.ManagedChannelOrphanWrapper - *~*~*~ Previous channel ManagedChannelImpl{logId=5, target=127.0.0.1:64792} was garbage collected without being shut down! ~*~*~*

can you provide some details about your environment? What JDK are you using, what command line, etc?

It happens in Ubuntu on bash with Open JDK 21, on a mac with zsh and Zulu JKD 25.0.2.fx-zulu and in the Colima Ubuntu Container on bash with Open JDK 21.

This error is probably the result of recent refactoring work I did in #8046.

It means a test created a gRPC ManagedChannel and didn't close it after. The stacktrace helps you track down where the ManagedChannel was initialized.

I'll clean it up when I get to it, but also happy for PRs if track down the problem test.
