It looks like PsiClass.getQualifiedName() is returning null for a class being added to the test profile.

Does anyone know what the test class/code which triggered this looked like? Currently I'm not able to reproduce this.

I have a small patch which will skip any PsiClass which doesn't return a qualified name, but I'd rather know what I'm potentially ignoring (could this be a bug in PsiClass)?

For reference : com.theoryinpractice.testng.configuration.TestNGRunnableState:264 - 
if (classes.size() > 0) {
  Map<String, Collection<String>> map = new HashMap<String, Collection<String>>();
  for (Map.Entry<PsiClass, Collection<PsiMethod>> entry : classes.entrySet()) {
    Collection<String> methods = new HashSet<String>(entry.getValue().size());
    for (PsiMethod method : entry.getValue()) {
      methods.add(method.getName());
    }
    map.put(entry.getKey().getQualifiedName(), methods);
  }

The map allows a null key to be added, however when this is used lower down inside TestNG, the Map.Entry's key is stored inside a Properties instance, which doesn't allow nulls and throws the NullPointerException.

getQualifiedName() returns null for anonymous and local classes.

Reproduced the problem with the following test class: 
public class EmptyMapTest {
  public void someMethod() {
    class FooTest {
      @Test(groups = "test")
      public void thisTestBreaksThings() {
        assert true;
      }
    }
  }

  @Test(dependsOnGroups = "test")
  public void thisTestTriggersABreak() {
    assert true;
  }
}

When running the TestNG plugin attempts to resolve the dependencies of the thisTestTriggersABreak test method, the local class FooTest is pulled in as a dependent test container.

The plugin has been patched to trap and report such dependency issues in the Diana branch, for some reason I can't currently compile locally so once I confirm the problem is trapped cleanly, I'll back port the change to Selena and resolve the issue.
