This could be moved into ReadZip.  I do not believe we have a specific test and it is trivial

Yes CopyZipFile already exercises Zipfile.ZipInputStream so it is safe to retire CopyJar (though CopyZipFile could use a junit conversion ;-)

I believe you meant GetDirEntry.java not DirEntry.java?

Having a test that specifically validates we can read META-INF is not a bad thing, but I suspect we have a test that already does that if not in the java/util/zip tests or java/util/jar tests.  If not we should keep it but merge it as you suggest
