Description

The harmony method java.text.Collator.compare(String, String) returns 0 with both 'null' while RI throws NPE.

================= test.java ======================
import java.text.*;

public class test {
public static void main (String[] args) throws Exception {
RuleBasedCollator rc = new RuleBasedCollator("< a< b< c< d");
try

{ System.out.println("res = " + rc.compare(null, null)); }

catch (Exception e)

{ System.out.println("1: " + e); }

try

{ System.out.println("res = " + rc.compare("a", null)); }

catch (Exception e)

{ System.out.println("2: " + e); }

try

{ System.out.println("res = " + rc.compare(null, "a")); }

catch (Exception e)

{ System.out.println("3: " + e); }

}
