Getting `ProviderNotFoundException` while comparing .aar files

See original GitHub issue

Was trying to find a diff of one of the privately published library in my team. I’m getting the following stacktrace.

> ./diffuse diff --aar catlib-2.2.1.aar catlib-2.2.4.aar

Unfortunately, due to a bug/missing feature in Java’s implementation of zip filesystems, you have to use Java 11 or newer for aars or aabs.
