Bug#281602: libgcj5: SocketChannel.get(ByteBuffer) returns 0 at EOF.

[Sebastian Andersson <sa@hogia.net>]

Package: libgcj5
Version: 3.4.2-3
Severity: normal


When a SocketChannel reaches EOF, the get method doesn't return -1 as it
should.

Example program:
------------------------------------------------------------------------
import java.net.*;
import java.nio.*;
import java.nio.channels.*;
import java.util.Iterator;

public class Server {
    public static void main(String[] args) {
        try {
            Selector serverSelector;

            serverSelector = Selector.open();
            ServerSocketChannel ssc = ServerSocketChannel.open();
            ssc.configureBlocking(true);
            ssc.socket().bind(new InetSocketAddress(2003));
            SocketChannel sc = ssc.accept();
            sc.configureBlocking(true);
            while(true) {
                ByteBuffer bb = ByteBuffer.allocate(100);
                int i = sc.read(bb);
                System.out.println("Read : " + i + " bytes.");
                for(int j = 0; j < i; j++) {
                    System.out.print((char)bb.get(j));
                }
                if(i < 0) {
                    System.out.println("Closing : " + i);
                    sc.close();
                    return;
                }
            }
        } catch(Exception ex) {
        }
    }
}
