Description

Our Jenkins builds fail sporadically without providing a message:

17:08:28 [WARNING] Rule 4: org.apache.maven.plugins.enforcer.DependencyConvergence failed with message:
17:08:28 null

Looking at the code, I suspect that this can happen on line 132 of the rule when some underlying exception is caught which itself does not provide a (localized) message.
As the plugin does not include the cause (unless failFast is set), you will just see a null message.
