Description

The following seems to result from a project-reference cycle between a plugin project and itself. For instance, when the compiler plugin build configures an earlier version of the compiler plugin, a project reference is established between the compiler plugin and itself in the reactor. This results in a StackOverflowError when trying to calculate the concrete state for the compiler plugin project, since it's trying to traverse project references (to itself).
