--------------------------------------------------------------------------

         Key: HARMONY-692
         URL: http://issues.apache.org/jira/browse/HARMONY-692
     Project: Harmony
        Type: Improvement

  Components: Classlib  
    Reporter: Vladimir Ivanov
    Priority: Minor


The j2se spec says for the java.util.logging.Handler.isLoggable(LogRecord record)
'It will return false if the LogRecord is Null'
but harmony print additional error message that can confuse user.
=============== test.java ======================
import java.util.logging.*;
public class test  {
    public static void main (String[] args) { 
        System.out.println("isLoggable(null) = " + new ConsoleHandler().isLoggable(null));
    }
}
============================================
