Hello [~cosmin79]
Thank you for your report.
The example you provided does not compile. Note that you must use Java 8. If
you can provide something we can run on Java 8, we can debug it.
Your best bet is to provide a PR on GitHub.

> Commons compress 1.26.0 gives unexpected Corrupted TAR archive

> That code shows that occasionally the header is wrong (the tar entry name
> contains gibberish bits) which makes me think that `getNextTarEntry()` can be
> faulty.
>
> Running that code with commons compress 1.25.0 works as expected. So it's
> probably something added since November. Note that this is something related
> to parallelism - using an executor service with a single thread doesn't
> suffer from the same error. The tgz to decompress doesn't really matter - you
> can use a manually created one worth a few KBs.
