> 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
