Update time4j to v4 and test components #1
Description
MenoData mentioned:
Maven search shows that the newer versions v4.28 or later all exist:

@pholthau I vaguely remember that there was once a build problem with v4.27.x. Maybe you consider to update your dependency to <time4j.version>[4.28,5.0)</time4j.version> or similar (this would actually grab v4.34, soon v4.35).
