TarGzExporter wrong packing of paths with more than 100 characters

Prefixes of long paths (> 100 chars) are ignored when unpacking archives with tar on linux.

Packing "moreThan100/long/path/to/file.class" with TarGzExporter, is unpacked by linux tar as "long/path/to/file.class".
Where "long/path/to/file.class" is just bellow 100 chars.
