RFR: 8276123: ZipFile::getEntry will not return a file entry when there is a directory entry of the same name within a Zip File

[Lance Andersen]

Hi all,

This patch addresses a regression introduced in JDK 15 via JDK-8242959 where you can no longer access a file entry contained within a Zip file when there is also a directory entry with the same name via ZipFile:getEntry(). 

 Once fixed, the behavior will be consistent with earlier JDK releases. 

Mach5 tiers 1-3 have been run without failure

Best
Lance
