During some recent refactoring, JDK-8025306, an unnecessary initialization of the InetAddress classes was added to the NIO implementation. InetAddress classes only need initialization for network channel types.

$ cat Test.java
public class Test {
    public static void main(String[] args) throws Exception {
        java.io.File file = new java.io.File(".");
        java.nio.channels.FileChannel fc = java.nio.channels.FileChannel.open(file.toPath());
    }
}
$ javac Test.java
