Quartz dependency version definition is flawed

Module hippo-ecm-repository-modules defines the following dependency:

<dependency>
<groupId>opensymphony</groupId>
<artifactId>quartz</artifactId>
<version>[1.5.1,)</version>
</dependency>

However, when a project dependency uses a version 1.6.6 for example, Hippo code depending on 1.5.x API breaks.
