sun.nio.ch.DefaultAsynchronousChannelProvider throws "platform not recognized", is it not implemented?

[Palle Girgensohn]

Hi

I cannot start tomcat 7.0.47 on FreeBSD with openjdk7. Here's a simple isolated example. It seems to me that it is just not implemented? Any ideas if there is anything we can do to work around this problem or perhaps fix it?

$ cat Foo.java
import java.nio.channels.AsynchronousServerSocketChannel;

class Foo {
    public static void main(String[] args) throws Exception {
        AsynchronousServerSocketChannel.open();
    }
}

$ javac Foo.java
$ java Foo
Exception in thread "main" java.lang.InternalError: platform not recognized
