We are using a maven build setup, all modules do have explicit names.
The build only collects findbugs, pmd and checkstyle warnings.
The checkstyle, PMD and findbugs views shows a correct structure.
In the analysis collector view (that aggregates everything) however, a minority of the warnings is spread through the tree with correct module names (1). The majority is assigned to "Default Module". Drilling into "Default module" shows the correct module names as childs. But the warnings assigned to (1) are not shown.
