Class LogbackWeakDependency

java.lang.Object
  org.neo4j.kernel.logging.LogbackWeakDependency

public class LogbackWeakDependency
extends Object

This class is here since kernel has a weak dependency on logback, i.e. it will be used if available, otherwise a fallback will transparently be used in its place. So even if some other classes this class may refer to are available at compile time, it cannot be written in a way that assumes them being there. For example it cannot import those classes, but should resolve them by reflection instead.
