--------------------------------------------------------------
[~ggregory] for what it's worth, that the PR in.
Argh, helps if the tests are in the correct location!
What happens when rushing to get to bed... sorted now. JDK 14 doesn't appear to
build, the rest do.

> SevenZFile fails with encoded header over 2GiB

> Issue Type: Bug
> Components: Archivers

> Reporter: A Kelday
> Priority: Minor
> Attachments: HeaderChannelBuffer.java

> 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).
