> The reason for this bug is some inconsistency in the Comparator used
> internally when building Clover reports. This is e.g., an asymetry in +1/-1
> when exchanging compare() parameters.
> There is already an issue open at Atlassian:
> https://jira.atlassian.com/browse/CLOV-1368
> Marek Parfianowicz asked me to try this out, but I have to add snapshot
> builds to our IVY config. Currently I also have an issue open at Atlassian to
> update our License, so we can use newer versions @ ASF.
