This problem has been encountered already...
There is a logic problem in Sun's code. 

A quick hack for FreeBSD is to just remove everything except the line 
marked with >>>>>>.

in src/solaris/sun/nio/ch/DefaultSelectorProvider.java

public class DefaultSelectorProvider {

    /**
     * Prevent instantiation.
     */
    private DefaultSelectorProvider() { }

    /**
     * Returns the default SelectorProvider.
     */
    public static SelectorProvider create() {
	PrivilegedAction pa
	    = new GetPropertyAction("os.version");
	String result = (String) AccessController.doPrivileged(pa);
        String[] numbers = result.split("\\.", 0);
        if (numbers[1].compareTo("7") < 0)
>>>>>>>>>>>            return new sun.nio.ch.PollSelectorProvider();
        else
            return new sun.nio.ch.DevPollSelectorProvider();
    }

}

later
