Stefan Bodewig resolved COMPRESS-129.
-------------------------------------

    Resolution: Fixed

For non-ZIP64 entries, i.e. for ZIPs Commons Compress 1.2 can actually deal with, svn revision 1151104 should work.

The zip64 branch already contains the more general solution.

> Issue:
> "java.io.EOFException: Truncated ZIP entry: <some entry>" will be threw while extracting a zip file that contains a entry with size larger than Integer#MAX_VALUE bytes (about 2 GB). After the big entry has been read, then try to get next entry by calling ZipArchiveInputStream#getNextZipEntry(), and it throws that EOFException.
> Cause:
> before getting next zip entry, ZipArchiveInputStream tries to close the current entry and in the close- method it use the field "bytesReadFromStream" to ensure all entry bytes are read, however the field "bytesReadFromStream" is a integer, that means it is already overflowed and it leads to a false ensure result.
> Solution suggestion:
> instead integer using long for "bytesReadFromStream" and possibly for "readBytesOfEntry" too.
