Description

I created an archiv with 7zip 9.20 containing the compress-1.7-src directory. Also tried it with 1.6 version and directory. I

downloaded the zip file and reziped it as 7z. The standard setting where used:
Compression level: normal
Compression method: lzma2
Dictionary size: 16 MB
Word size: 32
Solid Block size: 2 GB

I get an exception if I try to open the file with the simple line of code:
SevenZFile input = new SevenZFile(new File(arcName));

Maybe it is a bug in the tukaani library, but I do not know how to report it to them.
The exception thrown:
