FULL PRODUCT VERSION :
java version "1.4.1-beta"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.1-beta-b14)
Java HotSpot(TM) Client VM (build 1.4.1-beta-b14, mixed mode)

FULL OPERATING SYSTEM VERSION : Microsoft Windows 2000 [Version 5.00.2195]

DESCRIPTION OF THE PROBLEM :
I am able to declare a method as throwing an exception, even though the
interface it is implementing from higher in its inheritance tree does not
have any exceptions declared for that method.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Try to compile the attached source code.

EXPECTED VERSUS ACTUAL BEHAVIOR :
The code compiles, but shouldn't.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No error message. The code successfully compiles, even though it shouldn't.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
import javax.swing.AbstractAction;
import java.awt.event.ActionEvent;

public class TestAction extends AbstractAction {

public void actionPerformed(ActionEvent e) throws Exception {
}
}
---------- END SOURCE ----------

With JDK1.3.1_04, it gives the following.

C:\>javac TestAction.java
TestAction.java:6: actionPerformed(java.awt.event.ActionEvent) in TestAction can
not override actionPerformed(java.awt.event.ActionEvent) in javax.swing.Abstract
Action; overridden method does not throw java.lang.Exception
        public void actionPerformed(ActionEvent e) throws Exception {
                    ^
1 error

Release Regression From : 1.3.1_04
The above release value was the last known release where this
bug was known to work. Since then there has been a regression.
