Bug Report

Describe the Bug

When trying to set up a simple connector sample, the build was successful. However, upon attempting to run it, the connector started successfully but then instantly shut down.

Expected Behavior

The connector should start and remain active, ready to accept requests as described in the documentation.

Observed Behavior

hey, thanks for reporting, apparently the reason is that no threads have been launched so the runtime have nothing that keeps it alive.
A short fix would be to add a dependency like implementation(libs.edc.http), that will make the runtime running.

It looks to be caused by the fact that the previous implementation of the HealthCheckService (one of the services provided by the boot module) was scheduling threads, but now it's not doing it anymore.

I will provide the fix in the sample.
