There is a unsolveable race condition between the connection state and sendPacket(), i.e. the connection could go down, right after the method calling sendPacket is called, but before sendPacket() is invoked. Before this change, sendPacket() has thrown an unchecked IllegalStateException, which could be ignored by the Smack user, who would also not notice the race condition. We have decided to throw a checked Exception in this case now, to make the Smack user aware of this situation. SMACK-426
