Re: Why class implementing NamespaceContext compiles in Java 6, but
not Java 5?
I have a class that implements javax.xml.namespace.NamespaceContext.
As far as I can tell, this interface has not changed between Java 5
and Java 6 (specifically 1.5.0_11 and 1.6.0_07). My class implements
the three methods of the interface, and puts the "@override"
annotation on each one of them.
When I compile this class with Java 6, either from within eclipse or
standalone, it compiles and runs fine. When I compile it with Java 5
(eclipse and standalone), it complains "method does not override a
method from its superclass", for all three interface methods. What am
I missing here?
AIUI, in Java 5 @Override only applied when the class extended a superclass,
not when it directly implemented an interface. This was changed for Java 6.
Note that if a method overrides a method from a superinterface but
not from a superclass, using @Override will cause a compile-time error.
That Java 6 does not conform to this is apparently an error, unless there's an
addendum I haven't found yet.
