Original Source

Reports socket resources that are not safely closed. Socket resources reported by this inspection include java.net.Socket, java.net.DatagramSocket, and java.net.ServerSocket.

By default, the inspection assumes that the resources can be closed by any method with 'close' or 'cleanup' in its name.

Example:

byte[] getMessage(ServerSocket socket) throws IOException {
    Socket client = socket.accept(); //socket is not closed
    return client.getInputStream().readAllBytes();
  }

Use the following options to configure the inspection:

  • Whether a socket is allowed to be opened inside a try block. This style is less desirable because it is more verbose than opening a resource in front of a try block.
  • Whether the resource can be closed by any method call with the resource passed as argument.
