*********calling log.i(null,null) results in null pointer exception *****************

Please describe the problem in detail. Be sure to include:
I was debugging an application and the code could result something like the following:
String s = null;
/*..... */
log.i(s,s); /* this causes a null pointer exception */
Test case:
package com.testy;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class test extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String i = null;
/* trigger the null pointer de-ref */
Log.i(i,i);
}
}
