NetBeans Under OpenJDK 7 On OS X - Dual Display

[Max (Weijun) Wang]

It seems even the simplest networking code fails.

$ cat ~/tmp/A.java
class  A {
   public static void main(String[] args) throws Exception {
     new java.net.ServerSocket(10000).accept();
   }
}

$ java A
Exception in thread "main" java.net.SocketException: Invalid argument
	at java.net.PlainSocketImpl.socketAccept(Native Method)
	at  
java.net.AbstractPlainSocketImpl.accept(AbstractPlainSocketImpl.java: 
364)
	at java.net.ServerSocket.implAccept(ServerSocket.java:513)
	at java.net.ServerSocket.accept(ServerSocket.java:481)
	at A.main(A.java:3)

Don't know why. The problem comes from C function NET_Accept, which is  
mentioned in these files:

    jdk/make/java/net/FILES_c.gmk
       Include bsd_close.c when OS_VENDOR is FreeBSD
    jdk/src/solaris/native/java/net/bsd_close.c
       Defines a version of NET_Accept
    jdk/src/solaris/native/java/net/net_util_md.h
       Declares NET_Accept, using impl of bsd_close.c or JVM_Accept  
depending on defined(__FreeBSD__)

I'm not familiar with BSD C coding. Anyway on Mac OS_VENDOR is Apple.
