           Summary: Java 1.5 compatibility issue - @Override
           Product: Swift
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: General

When trying to build swift with Java 1.5, I receive errors related to the use
of @Override.

In Java 1.5 you can only use the @Override annotation when overriding methods
of a class. If the method is defined in an interface rather than a superclass,
a compilation error will occur. (1.6 allows @Override for both classes and
interfaces)

I ran into this when trying to build swift on sisboombah. Patch attached.

java version "1.5.0_14"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_14-b03)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_14-b03, mixed mode)
