BUG: 4681995 add support zipping/unzipping large files

[Robert McIlhargie]

Is anyone working on this?

I currently get an exception "invalid entry size(expected ..." when I try to unzip files that are larger than 4.29GB (0xFFFFFFFF) bytes that 
have been compressed using PKZip. In looking at the code for ZipInputStream, its not parsing out the Zip64 information
in the extra information area for the ZipEntry. I've read through the PKZip specification and written some code to parse out the byte array
of extra information that is stored in the ZipEntry class to get the 64-bit file sizes.

Is there anyone I should coordinate on fixing this with?

Thanks.
