I think I would replace the sentence "Additionally ..." with "Consequently, a ZipInputStream that reads from a ZIP file may read ZIP file entries that are not in the ZIP file's central directory".

> Replacing the sentence "ZipFile may be used ..." is okay but I don't think the proposed text works. The API note starts with text to say that a ZipInputStream doesn't read the CEN so saying "correctly reads from the central directory" is very confusing. ZipInputStream is a JDK 1.1 era API, it is what it is and would be disruptive to deprecate.

Thank you, I will work on this
