Gary D. Gregory commented on COMPRESS-619:
------------------------------------------
Is there a way to manufacture a test fixture we can use in unit tests? Without
having to store a giant file in git or create a huge temp file? Maybe a hacked
file?
> Large SevenZFile fails When Next Header Size is Greater than Max Int

> When reading a large file (42GB) the following stack trace is produced:
>
> {code:java}
> java.io.IOException: Cannot handle nextHeaderSize 4102590414

> The file was produced using the SevenZOutputFile class and contains a large
> number of very small files all inserted using copy compression. It passes the
> 7z tests and has the following statistics:
>
> {code:java}
> Files: 40872560
> Size: 43708874326
> Compressed: 47811464772
> {code}
> It is failing because a ByteBuffer can't be created that is large enough with
> something over max integer in size to do the CRC check.
