FULL PRODUCT VERSION :
java version "1.5.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b50)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b50, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
The class Test overrides the compareTo() methods of File. In B40 and earlier there were 2 seperate methods in File - compareTo(Object) and compareTo(File).

My code overrides both because it needs to compare my class to things other than File (in particular I have an interface to encompass normal files and jar entries, but that is not shown here)

Now (as of B50) that File implements Comparable<File> the compareTo(Object) method is a bridge method, and I can't override it.


REGRESSION. Last worked in version tiger-beta

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
javac -source 1.4 Test.java

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
The file compiles successfully.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Test.java:6: compareTo(java.lang.Object) in Test cannot override compareTo(java.lang.Object) in java.io.File; attempt to override a bridge method
   public int compareTo(Object o) { return 0; }
              ^

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------

import java.io.File;

public class Test extends File {
   public Test(String s) { super(s); }
   public int compareTo(File f) { return 0; }
   public int compareTo(Object o) { return 0; }
}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
I wish there was one.
