I was investigating about a possible bug of Netbeans when this exception occurred. I don't know if the problem that I was investigating for is related to this exception or not. In any case I write you a detailed description about it and how to reproduce the exception.

The problem:
When the pom of a maven project has a dependency problem the project structure is not correctly shown int the "Projects" panel. The project folders "source" and "test" are missed and it is not possible to access to the java sources.

Steps to reproduce it:
1. First of all I created a new fresh Netbeans profile (8.0.1).
2. Starting Netbeans it advices that there's the new version (8.0.2). I selected to update it.
3. After the restart it founds other updates. Again I selected to do them.
4. Netbeans restarts again so at this point it should have a fresh 8.0.1 profile updated to the version 8.0.2.
5. I created a new  Maven Java Application
6. I opened the pom and voluntarily put the following fake dependency:
