Motivation: As reported in #2331, some query operations in NetworkInterface takes much longer time than we expected. For example, specifying -Djava.net.preferIPv4Stack=true option in Window increases the execution time by more than 4 times. Some Windows systems have more than 20 network interfaces, and this problem gets bigger as the number of unused (virtual) NICs increases. Modification: Use NetworkInterface.getInetAddresses() wherever possible. Before iterating over all NICs reported by NetworkInterface, filter the NICs without proper InetAddresses. This reduces the number of candidates quite a lot. NetUtil does not query hardware address of NIC in the first place but uses InetAddress.isLoopbackAddress(). Do not call unnecessary query operations on NetworkInterface. Just get hardware address and compare. Result: Significantly reduced class initialization time |
