> there're many places in this module could be optimized by toASCIIUpper(Lower)Case().
> Such as, 
> JarFile - regionMatches, only check for ".SF", ".DSA", "MANIFEST.MF"
> InitManifest - toLowerCase,  name of manifest properties is {A-Z} | {a-z} | {0-9} | -
> Attributes - toLowerCase, same as above
> I compress patches into a zip since there're 2 new-add files.
