[take two!]

Tom,

This specific area of code was changed recently due to CR 7035556 [1], changeset [2], and this issue was discussed during the code review [3].

Essentially, bind() already closes the impl internally before throwing the exception. Does this resolve the issue for you? Or do you still see potential to leak?

There appears to be a socket leak in both DatagramSocket and
MulticastSocket constructors. Both classes have constructors that create
a socket and then attempt to bind. The bind can fail with a variety of
exceptions none of which are caught by the constructor. Thus, the actual
system socket that was allocated by impl.create() is never closed.

My fix was to wrap a try-finally around the bind call and call close()
if isBound is false.

public DatagramSocket(SocketAddress bindaddr) throws SocketException {

// create a datagram socket.

createImpl();

if (bindaddr != null) {

try {

bind(bindaddr);

} finally {

if( !isBound() )

close();

}

}

}
