The available() method returns pos+super.available().
It should return (buf.length-pos)+super.available(), like e.g. BufferedInputStream.

import java.io.*;

public class PushbackInputStreamTest
extends PushbackInputStream
{
  public static final String nullFilename
    // SYSTEM DEPENDENCY. Choose one or the other
    = "nul" // Windows, W95, NT, OS/2
// = "/dev/null" // Unix &c
    ;
  public static void main(String[] args)
  {
    try
    {
      InputStream is = new PushbackInputStream(new FileInputStream(nullFilename));
      int avail = is.available();
      if (avail > 0)
        System.out.println("FAIL: avail="+avail);
      else
        System.out.println("PASS: avail="+avail);
      is.close();
    }
    catch (IOException ioe)
    {
      ioe.printStackTrace(System.err);
    }
  }
}
