| /** For method references with a type selector two searches are performed. |
| * Each of them may yield one of the following results: |
| * I) a good match |
| * II) a bad match more specific than a good match |
| * III) a bad match with no good matches |
| * IV) no applicable method found |
| * |
| * Whether a match is considered to be good or not depends on the staticness |
| * of the matched method. The expected result of the first search is a static |
| * method. The expected result of the second search is an instance method. |
| * |
| * If the most specific method has the wrong staticness but there is an |
| * applicable method with the right staticness then we have the (II) case. |
| * The (III) case is reserved for those cases when the most specific method |
| * has the wrong staticness but there is no applicable method with the right |
| * staticness. |
