I am experimenting a bug with generating new ObjectId in my project.
The first invocation takes about 15 - 45 secs, but then (posterior invocations works as usual) everything is ok.
This happens only when I anchor my laptop to my smartphone to access Internet!

Seems like NetworkInterface.getNetworkInterfaces() takes too much time to retrieve network information for the first time
ObjectId.class
579 Enumeration<NetworkInterface> e = NetworkInterface.getNetworkInterfaces();

here is my code:
long init = System.currentTimeMillis();
new ObjectId();
LOG.info("ObjectId generated in " + (System.currentTimeMillis() - init) + " ms");

Please fix it
