183389 – [PATCH] java/openjdk7 fails using nio.ch.DefaultAsynchronousChannelProvider

no flags

Tomcat's latest version, 7.0.47, seems to have changed to use
sun/nio/ch/DefaultAsynchronousChannelProvider.java

with FreeBSD's openjdk, this fails with a java.lang.InternalError: platform not recognized

tomcat 7.0.42 workes fine, but surely doesn't use the asynchronous channel stuff from nio.

Fix: This is already fixed for MaxOS, using kqueue(2). Just changing to accept the 
same lib for FreeBSD *seems* to help. The test case works. Tomcat works. But since this is 
"Asynchrounous Channel", maybe some more tests would be appropriate?
How-To-Repeat: $ 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
