See http://forums.java.net/jive/thread.jspa?threadID=29654&tstart=0 You can reproduce this issue running on Windows XP or 2003 with IPv6 enabled. --- begin code --- public class SockTest { public static void main(String[] args) throws Exception { ServerSocket ss = new ServerSocket(4444); Runtime.getRuntime().exec(new String[] {"notepad.exe"}); ss.close(); } } --- end code --- The above testcase spawns a notepad. Notepad inherits the handle to the socket, so if you try and re-execute the test if fails with "BindException: Address already in use". This is reproducible with Java SE 5, 6, and 7.
