IntelliJ has a check for this which works quite good. But in contrast ECJ from Eclipse has not. It would have been great to allow this check. Maybe check errorprone, maybe they have a rule already? Basically we could add this to forbiddenapis, but that would be a misnomer. All you need is a check if a static initializer of a class references a subclass in any (direct) way. The issue then happens if the subclass is initialized in another thread while the static initializer is running. So generally static initializers that refer to private child classes which cannot be seen befor the parent is initialized, are safe, but that's a detail and needs to be decided. The Codec Deadlock was exactly that problem, too. Unfortunately for this case a static tool won't have a chance, so a static tool alone is not a full solution. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
