> FindBugs notes that the Type class tries to use the ObjectType class before it has been initialised:
> {code}
> public static final BasicType CHAR = new BasicType(Constants.T_CHAR);
> public static final ObjectType OBJECT = ObjectType.getInstance("java.lang.Object");
> {code}
> Now both BasicType and ObjectType are sub-classes of Type.
> However FindBugs only complains about the ObjectType call.
> Perhaps this is because it uses a static method?
> The getInstance() method could be replaced with the equivalent:
> {code}
> public static final ObjectType OBJECT = new ObjectType("java.lang.Object");
> {code}
> But why does FindBugs not complain about the other references?
> Surely BasicType cannot be constructed until Type has been constructed?
> It's not (yet) clear what is going on here...
