Eclipse Kura Jenkins: build failures for RC build

Summary

We have encountered a couple of times during the last Eclipse Kura RC builds a failure due to java.nio.channels.ClosedChannelException hudson.remoting.Channel$CallSiteStackTrace: Remote call to JNLP4-connect connection from 10.40.23.233/10.40.23.233:37434

Steps to reproduce

Have a reference to Kura RC builds: https://ci.eclipse.org/kura/job/kura-release-candidates/job/kura-5-6-0-release-candidate/7/console

What is the current bug behavior?

It seems that the first run of an RC build fails. Re-executing, without any notable change, the build starts successfully.

What is the expected correct behavior?

All the RC builds should start successfully
