/* @test
 * @bug 4287596
 * @summary Unit test for "Pluggable Connectors and Transports" feature.
 *
 * When a transport service is deployed the virtual machine machine
 * is required to create an AttachingConnector and ListeningConnector
 * to encapsulate the transport. This tests that the connectors are
 * created and that they have an "address" argument.
 *
 * @build GeneratedConnectors NullTransportService
