Seems jar.getDirectories() can contain null values, if there is a jar with META-INF/services/subfolder, but META-INF/services itself does not contain any files. In this case the directories() map contains a key for "META-INF/services" but a null value (which is the map which is null here) Signed-off-by: Christoph Rueger <chrisrueger@gmail.com> improve test Signed-off-by: Christoph Rueger <chrisrueger@gmail.com>
