--------------------------------



Hello Bela Ban, 

I was testing your solution in a Samsung Q1 and it still fails. The exception occurs inside getInterfaceAddresses() so you must catch NPE in method call:

if (i.isUp()) {

	List<InterfaceAddress> inet_addrs = null;

	try {

		inet_addrs = i.getInterfaceAddresses();
	} catch (Exception e) {

		System.out.println("JVM Bug catched");
	}

	if ((inet_addrs != null) && !inet_addrs.isEmpty()) { // fix for VM crash - suggested by JJalenak at netopia.com
		s.joinGroup(group_addr, i);
		this.log.trace("joined %s on %s", group_addr, i.getName());
	}
}

Best regards
