Subject [jira] Created: (HARMONY-1515) [classlib][beans] EventSetDescriptor(.., Method) throws IntrospectionException on Harmony end creates object on RI

[classlib][beans] EventSetDescriptor(.., Method) throws IntrospectionException on Harmony end
creates object on RI
------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-1515
                 URL: http://issues.apache.org/jira/browse/HARMONY-1515
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Vladimir Ivanov


The constructors EventSetDescriptor("get", Class.class, (Method[])null, m, m))
EventSetDescriptor("get", Class.class, null, m, m, m))
EventSetDescriptor("get", Class.class, (MethodDescriptor[])null, m, m))
creates objects on RI and throws IntrospectionException (NPE in the case of 3) on Harmony.
I suggest to follow RI.

Note, some Harmony unit test for EventSetDescriptor failed due to this issue.

===================== test.java =========================
import java.beans.*; 
import java.lang.reflect.*;

public class test { 

    public static void main (String[] args) throws Exception { 
        Method m = Object.class.getMethod("notify", null);
        try { 
            System.out.println("res = " + new EventSetDescriptor("get", Class.class, (Method[])null,
m, m));
        } catch (Exception e) { 
            System.out.println("exception: " + e); 
        } 
        try { 
            System.out.println("res = " + new EventSetDescriptor("get", Class.class, null,
m, m, m));
        } catch (Exception e) { 
            System.out.println("exception: " + e); 
        } 
        MethodDescriptor md = new MethodDescriptor(m);
        try { 
            System.out.println("res = " + new EventSetDescriptor("get", Class.class, (MethodDescriptor[])null,
m, m));
        } catch (Exception e) { 
            System.out.println("exception: " + e); 
        } 
    } 
}
