Class ReservedPorts

java.lang.Object

org.terracotta.utilities.test.net.ReservedPorts

public final class ReservedPorts
extends Object

Identifies reserved ports on a platform.

More recent releases of Microsoft Windows has the ability, by API or command, to reserve a port for use by an application. While typical usage would be to reserve an ephemeral/dynamic port, reservation is not restricted to these ports so reserved ports need to be avoided in PortManager processing.
