> When reading what some may call a large encrypted 7zip file (1.2TB with 22
> million files), the read fails at the header stage with the trace below. Is
> this within the spec? I've written some code to handle it, because I did
> actually need to extract the file in java. If that's of any use I can provide
> it (it's a naive wrapper that just pages in a buffer at a time).
