> [ProjectSorter|http://svn.apache.org/repos/asf/maven/maven-3/trunk/maven-core/src/main/java/org/apache/maven/project/ProjectSorter.java] skips vertexes where versions don't match and thus produces incorrect results.
> For example, if A depends on B:1.0 but B is resolved to 1.1 (via conflict resolution or dependency management) then A->B:1.0 is lost.  One suspect could be {{isSpecificVersion}} which returns true for 1.0, which isn't a specific version like [1.0], so this vertex gets lost as B:1.0 doesn't exist.
