> When loading a .7z file with correct headers and without files info headers 
> using the SevenZFile class, a NullPointerException is thrown when calling 
> getEntries or getNextEntry, because the archive.files member of SevenZFile is 
> null. Ideally, a subclass of IOException should be thrown in this case.
> I attached an example file we encountered in our file processing pipeline, 
> which causes the exception.
