It's been happening several weeks already, that a Java process that being executed within Maven command, get killed randomly, as the Jenkins slave disconnects the connection unexpectedly, with error:

WARNING: Exception while copying in thread: Copier for /127.0.0.1:{RANDOM PORT}
java.net.SocketException: Connection reset

at java.io.FilterInputStream.read(Unknown Source)
at java.io.FilterInputStream.read(Unknown Source)
at hudson.remoting.forward.CopyThread.run(CopyThread.java:30)

Looking at Job console, we see that the Maven process completes, but the inner Java thread is terminated:
