Apt @Override annotation

Question

Hello!
I am having the following problem with apt: if I run it against an input file which uses the @Override annotation, I get the following warning:
warning: Annotation types without processors: [java.lang.Override]More specifically: I have the following input file:
public class test {
    @Override
    public String toString() {
        return super.toString();
}and I run apt on it:
bash-3.2$ apt -XListAnnotationTypes -XPrintFactoryInfo -XPrintAptRounds ~/work/test.java
apt Round : 1
filenames: [/user/fabratu/home/work/test.java]
options: com.sun.tools.javac.util.Options@e5b723
Set of annotations found:[java.lang.Override]
Factory com.sun.istack.internal.ws.AnnotationProcessorFactoryImpl matches nothing.
warning: Annotation types without processors: [java.lang.Override]
1 warningMy question is: how to get rid of the warning? This gets especially annoying when I develop my own annotations and annotation processors, and when I run apt against inputs that are valid from my processors' point of view, I still get a warning.
One solution would be just to add @Override to the supportedAnnotations list of my factories (or directly add "*") but I don't want to do that.
Initially I thought that there would be some AnnotationProcessorFactory that processes @Override somewhere inside the JDK jars. That's why I've tried:
bash-3.2$ apt -XListAnnotationTypes -XPrintFactoryInfo -XPrintAptRounds -cp $CLASSPATH:$JAVA_HOME/lib/* ~/work/test.java
apt Round : 1
filenames: [/user/fabratu/home/work/test.java]
options: com.sun.tools.javac.util.Options@15a8767
Set of annotations found:[java.lang.Override]
Factory com.sun.istack.internal.ws.AnnotationProcessorFactoryImpl matches nothing.
warning: Annotation types without processors: [java.lang.Override]
1 warningAs you can see, no luck here.
Any clues?
I use JDK 1.6.0_02

then you could write a dummy processor that claims all the standard annotations and does nothing. This would be better (IMHO) than bundling that functionality in with your actual processor. (Keep the worker part separate >from the bit that works around the annoying warnings.Ok, that could work. Thanks for the idea.
So, this is a known issue for apt and JDK 1.5?Yes, apt has always behaved that way.
In retrospect, at least the annotations that come with the platform, like @Override and @Deprecated, should have been excluded from that warning. The warning itself by default is overkill; javac only emits the analogous warning if an annotation processing lint option is used.
