Subject: [PATCH 1/2] ITPLAT-399 Systemd cleans up files in /tmp older than 10
 days. This removes the /tmp/.java_pid* file which is the socket created by
 the JVM that facilitates thread dumps. This file is never recreated once it's
 deleted, and the only way to recreate it and restore thread dump
 functionality is to restart the JVM. If using OpenJDK there is no `-F` option
 to force thread dumps which bypasses the socket. Once the file is deleted
 there is no way to take a thread dump on OpenJDK until a restart is
 performed. This commit excludes required java hooks including the pid file
 from systemd's cleanup. For more info:
