JarFile.entries() and JarFile.stream() return all the entries; they are not
filtered. Your example would work if the JarFile is constructed without a
Release argument or with the Release.BASE argument. The assertion would fail
if it’s constructed with any other Release argument. Adding a filter and a map
to the stream pipeline would make your example succeed with all values of
Release.
