Hi,
Thank you for explanation.
I'll fix it soon.
Thanks,

Thanks for bringing this to our attention, Alan. Roman is right - the
code in question should not compile and we should change it as he
suggests so that it is correct.
(For people interested in the gory details, the method
<T extends Annotation> T getAnnotation
<http://java.sun.com/javase/6/docs/api/java/lang/reflect/Constructor.html#getAnnotation%28java.lang.Class%29>(Class<T>
annotationClass)
returns T only if it is called on a properly generic variable, such as a
Constructor<?> or Constructor<? extends Foo> or Constructor<E>. If it is
called on a plain Constructor with no type parameter, then that is a
"raw type", and the return type is "erased" to Annotation. So something like
ConstructorProperties annotation =
constructor.getAnnotation(ConstructorProperties.class)
should not compile if constructor is declared as Constructor rather than
Constructor<?> or whatever.)

When trying to compile OpenJDK with the Eclipse compiler, I noticed two
compiler errors related to generics. It turned out that the code there
is invalid and only javac (incorrectly) accepts it. See the following
bug reports for details:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=212147
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6400189
The attached changeset fixes the problem. Could this be included?
