The problem sounds like one already reported. Is it possible that you're running with mvn3? Can you please try the same using the latest m2 version?
2.2.x is compatible with jdk5 and m2; all major releases (very probably all future minor releases of the 2.x branch too) will drop m2 and jdk5 support.
