The documentation of java.net.Socket says nothing about 0.0.0.0 address,

http://java.sun.com/j2se/1.4.2/docs/api/java/net/DatagramSocket.html
"If the IP address is 0.0.0.0, the socket will be bound to the wildcard
address, an IP address chosen by the kernel."
Hello Mikhail, they are different. New DatagramSocket("0.0.0.0",port) means
the datagram socket will be bound to "0.0.0.0", but new Socket("0.0.0.0",port)
means new a socket bound with a system free port and then connect to ("
0.0.0.0", port).
I didn't investigate Harmony implementation code, but I guess it's caused by
difference of system call. On windows, 0.0.0.0 is regarded as a "invalid
address", while on Linux, it's valid.
I'll take a deep look at the code later on.
So it's normal to use 0.0.0.0 and we have a bug.
Agree. I think we should follow RI this time.
