When I run "nmap (/pkg/local/bin/nmap -p <ServerSocket port no. Host)" portscanner utility against a java program, which is waiting on a ServerSocket accept() call, it causes the JVM to throw an exception "java.net.SocketException: Software caused connection abort".

Following is the stack trace o/p:
 
 java.net.SocketException: Software caused connection abort
    at java.net.PlainSocketImpl.socketAccept(Native Method)
    at java.net.PlainSocketImpl.accept(PlainSocketImpl.java:407)
    at java.net.ServerSocket.implAccept(ServerSocket.java:235)
    at java.net.ServerSocket.accept(Compiled Code)
    at auth.utauthd.CallBack.run(Compiled Code)
    at java.lang.Thread.run(Thread.java:472)

I have also attached the truss o/p of nmap command with this bug.
