Description

This change is intended to address an issue with port bind conflicts
specifically when VMs are restarted. Thus this change only specifies a
specific port when bouncing a VM. In this case we use a RMI port
outside the usual range of ephemeral ports for MacOS (49152–65535) and
Linux (32768-60999).

We typically try and use ephemeral ports everywhere. However,
sometimes an ephemeral port created during a prior start needs to be
used as a fixed port on subsequent bounces. In this case, ephemeral
ports that are allocated early may end up conflicting with these fixed
ports.
