Pulumi is not started from backed jar file

What happened?

I'm trying to run pulumi from precompiled jar file (following the guide here: https://github.com/pulumi/pulumi-java/ )

First I'm starting new project and could check that compilation is working and pulumi do the job.
Then I'm packaging exactly this project, and building farjar (repro guide is here: https://github.com/golosegor/pulumi-execute-from-jar-issue )

Then I'm trying to run pulumi with complid code from folder nearby: https://github.com/golosegor/pulumi-execute-from-jar-issue/blob/main/repro-folder/Pulumi.yaml and getting GRCP unavailable exception

Example

I've created a repro

Additional context

Start with the reproduction repository and repro-folder/Pulumi.yaml, then run the packaged jar through the Pulumi project as described in the report. Compare the successful compiled-project run with the far-jar run and trace the reported gRPC UNAVAILABLE failure. Done means the precompiled jar starts successfully from the nearby Pulumi project.
