test case

I am trying to compile OpenJDK using Eclipse. I get a compiler error on code that I think is correct (and javac compiles it without complaining). I'll attach an example.
Comment 1 Roman Kennke CLA 2007-12-07 04:54:58 EST 
It looks like the method Constructor.getAnnotation() returns a <T extends Annotation>, in this case ConstructorProperties, but the compiler treats it as Annotation instead.
Comment 2 Philipe Mulet CLA 2007-12-08 09:07:08 EST 
If you change slightly the test to remove dependency onto 1.6 lib (ConstructorProperties), with following snippet:

import java.lang.reflect.Constructor;
public class X {
	public static void main(String[] args) {
		try {
			final Class<MyConstructorProperties> propertyNamesClass = MyConstructorProperties.class;
			Constructor constr = propertyNamesClass.getConstructor();
			String[] propertyNames = constr.getAnnotation(propertyNamesClass).value();
		} catch (Exception ex) {
			// Ignore. 
		}
	}
}

@interface MyConstructorProperties {}

You will get both compile errors with javac1.5 and java1.6
D:>javac X.java -d ..\bin -Xlint
X.java:13: cannot find symbol
symbol  : method value()
location: @interface MyConstructorProperties
                        String[] propertyNames = constr.getAnnotation(propertyNamesClass).value();
                                                                                         ^

This is a dup of bug 167952. Pls see javac bug at:

Verified for 3.4M4 using build I20071210-1800.
Comment 6 Philipe Mulet CLA 2007-12-12 09:15:50 EST 
I got confirmation that the javac bug really is a plain javac bug.
