Basically, using a BufferedInputStream to read 0 bytes over a socket blocks with 1.5 whereas the same operation does not block using 1.4 ( See sample code below ). The netscape ldapjdk, and in turn apoc, relies on the behaviour seen in 1.4.

I can confirm that the problem does not occur for J2SE 1.5.0-beta-b32c and does occur for J2SE build 1.5.0-beta2-b45, so somewhere in between the behaviour changed.

The problem occurs does not occur if I use a plain InputStream, so I guess the suggestion is that the problem is down to some change in BufferedInputStream.


Sample Code
-----------

import java.io.*;
import java.net.*;

public class a
{
  public static void main( String[] inArgs )
  {
    try
    {
      InputStream theInputStream =
        new BufferedInputStream( new Socket( "sobuild.ireland.sun.com", 389 )
             .getInputStream() );
      byte[] theBytes = new byte[ 0 ];
      theInputStream.read( theBytes, 0, 0 );
    }
    catch( Exception theException )
    {
       theException.printStackTrace();
    }
  }
}
