Unable to generate unique id when range of ports are blocked - \
                org.apache.activemq.util.IdGenerator
---------------------------------------------------------------------------------------------------


                 Key: AMQ-3614
                 URL: https://issues.apache.org/jira/browse/AMQ-3614
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.5.1
            Reporter: Jason Sherman


org.apache.activemq.util.IdGenerator is unable to generate a unique id if a range of \
ports have been block. Currently there is only one strategy create this id if the \
canAccessSystemProps condition is true:

{code}
if (canAccessSystemProps) {
            try {
                hostName = InetAddressUtil.getLocalHostName();
                ServerSocket ss = new ServerSocket(0);
                stub = "-" + ss.getLocalPort() + "-" + System.currentTimeMillis() + \
"-";  Thread.sleep(100);
                ss.close();
            } catch (Exception ioe) {
                LOG.warn("could not generate unique stub", ioe);
            }
        } else {
            hostName = "localhost";
            stub = "-1-" + System.currentTimeMillis() + "-";
        }
{code}

No fallback strategy has been implemented if the canAccessSystemProp evaluates to \
true
