[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);
}
}
}
