[BUG]: Build breaks with ENOBUFS error after successful Java unit tests

[schuettecarsten]

What happened?

Build breaks with ENOBUFS error after successful Java unit tests. The Java build step works fine on a local machine. Tests are also executed sucessfully on the agent VM. The VM has 8 Cores and 16 GB RAM which should be more than enough, memory/CPU limites are not reached at all.

Hi, @DenisRumyantsev and team, any ideas what we can to to mitigate this issue? Our pipeline does not work on Microsoft hosted agents because we need some special software, and it also does not work on self-hosted agents (Azure VM) because of this issue.
