According to the docs on this routine, "If the first argument is
null, up to len bytes are read and discarded." However, it does
not do this. Instead, it throws an exception.

/* Example code */

import java.io.*;

public class Test
{
  public static void main(String[] args) throws IOException
  {
    byte[] buf = new byte[16];
    
    System.in.read(null, 0, 5); // Read and discard first 5 bytes
    System.in.read(buf, 0, 11); // Place next 11 bytes in buf
    System.out.write(buf, 0, 5); // Write out the first 5 bytes in buf
  }
}

/* Example output *
If there was no bug, we would see this:

  C:\> java Test <- we run the progran
  0123456789abcdef <- we enter this
  56789 <- and the program writes this

However, there is a bug, and instead we see this:

  C:\> java Test
  0123456789abcdef
  java.lang.NullPointerException
    at java.io.BufferedInputStream.read(BufferedInputStream.java:209)
    at Test.main(Test.java:9)

\* End of example */
