| Assigning to a static variable from a constructor is highly indicative of a bug, |
| or error-prone design. |
| |
| Common reasons are: |
| |
| 1. The field simply should be an instance field, and there's a bug. |
| |
| 2. An attempt is being made to lazily initialize a static field. In this case, |
| first consider whether lazy initialization is necessary: it often isn't. If |
| it is, doing it from a constructor is very hairy: the static field could be |
| accessed from a static method before the class is even initialized. Consider |
| using a memoized `Supplier`. |
