The java.net.URLConnection.setRequestProperty(String key, String value) allows
null key parameter.

Method's behavior for null key parameter is not documented.


Here is the javadoc comments for methods setRequestProperty and
getRequestProperty


    /**
     * Sets the general request property.
     *
     * @param key the keyword by which the request is known
     * (e.g., "<code>accept</code>").
     * @param value the value associated with it.
     * @since JDK1.0
     */



    /**
     * Returns the value of the named general request property for this
     * connection.
     *
     * @return the value of the named general request property for this
     * connection.
     * @since JDK1.0
     */



Here is the test demonstrating the bug:

------------------------ Test.java ---------------------------------------
import java.net.*;

class test
{
  public static void main(String args[])
  {
    URL url = null;
    URLConnection conn = null;
    String key = null;
    String value = "iso-8859-5";
   

    try {
     url = new URL("http://web2.javasoft.com/index.html");
     conn = url.openConnection();
    } catch(Exception e)
    {
System.out.println("Failed. Unexpected exception :" + e);
System.exit(-1);
    }


    try {
       conn.setRequestProperty(key, value);
    } catch(NullPointerException e)
    {
     System.out.println("Passed. OKAY");
     System.exit(0);
    }
    catch(Exception e)
    {
      System.out.println("Failed. Unexpected exception :" + e);
System.exit(-1);
    }
    
    if( value.equals(conn.getRequestProperty(key) ) )
    {
     System.out.println("getRequestProperty(null) = value");
    }
        
    System.out.println("Failed. No exceptions.");


  }
   
}

------------------------- Output from the test ----------------------------
getRequestProperty(null) = value
Failed. No exceptions.
