Hello,
As an indirect outgrowth of warnings cleanup day, various categories of
warnings can be eliminated by in the use of Cloneable types by
overriding the
Object clone()
method inherited from java.lang.Object with a covariant override such as
MyType clone()
Please review my changes for
7140820 Add covariant overrides to Collections clone methods
http://cr.openjdk.java.net/~darcy/7140820.0/
which add such covariant override clone methods to collections and a few
other classes in java.util. Doing a full JDK build with these changes,
I've also made alterations to other classes to remove now superfuous
casts (casts which are a javac lint warning!) and some unneeded
@SuppressWarnings annotations. I also cleaned up a few rawtypes
warnings while in editing files in java.util.
(Note that the old specListeners method in EventRequestSpecList.java was
much buggy; it cast an ArrayList from runtime.specListeners to a Vector.)
Thanks,
-Joe
