MulticastInputStream doesnot override public int available() throws IOException from java.io.InputStream

java.io.InputStream has a method implemented

public int available() throws IOException

{ return 0; }

and comments

• <p> A subclass' implementation of this method may choose to throw an
• {@link IOException}

  if this input stream has been closed by

• invoking the {@link #close()}

  method.
  *

• <p> The {@code available}

  method for class

  {@code InputStream}

  always

• returns {@code 0}

  .
  *

• <p> This method should be overridden by subclasses.

but org.openfast.session.multicast.MulticastInputStream
does not override this method.

Suppose to add such code to org.openfast.session.multicast.MulticastInputStream

@Override
public int available() throws IOException

{ System.out.println("!2"+socket.isConnected()); return buffer.remaining(); }
