The java.net.URL class does not perform url encoding/decoding, so the
java.net.URL.equals, java.net.URL.sameFile methods return false on URLs, that
are equal modulo url encoding.
The java.net.URL constuctor also does not throw any exceptions on non-urlencoded
parameters, thus creating an objects in an invalid state.

Here is the simple test demonstrating the bug:

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

class test
{

  public static void main(String args[])
  {
  URL url = null;
  URL url1 = null;
  
  try {
    url = new URL("http://web2.javasoft.com/some+file.html");
    url1 = new URL("http://web2.javasoft.com/some%20file.html");
  } catch(Exception e)
  {
    System.out.println("Unexpected exception :" + e);
    System.exit(-1);
  }

  if(url.sameFile(url1))
  {
    System.out.println("OKAY");
    System.exit(0);
  }
  else
  {
    System.out.println("Failed. ");
    System.exit(-1);
  }
}

}

---------------------- Output from the test --------------------
Failed.
