[Roland Mesde]

> Backporting JDK-8321156: Improve the handling of invalid UTF-8 byte sequences for ZipInputStream::getNextEntry and ZipFile::getComment.
> 
> Fixes invalid UTF-8 byte sequence handling in:
> - ZIP entry names within LOC file headers
> - ZIP file comments accessed through ZipFile::getComment
> 
> Behavior change: ZipFile::getComment now returns null when invalid UTF-8 sequences are detected during byte-to-String conversion.
> 
> Ran GHA Sanity Checks (passed) and related test (passed).
