Hi thank for reporting this.

dspot-maven-plugin has also another issue with TAF.

see below:

Investigating both.

DSpot was failing on metamutator because of the class in the default package.

When no filter is specified, DSpot computes a filter on the fly and this filter was not correct.

#748 should fix it.

I'm gonna open a new issue for TAF, because it is not the same issue.
