The CentralDirectoryFileHeader class override Object.clone() method but does not implement Cloneable. I'm not sure if this was intentionally not done by the developer, or if it was a mistake. pls check it.

I don't think there's any need for CentralDirectoryFileHeader to implement Cloneable. It's a package-private class and things are working fine as they are, including the single call to its clone() method. Thanks anyway for the proposal.
