It is possible, though generally not desirable, to execute methods or constructors prior to initialization. This can happen when a class hierarchy contains a circularity in its static initialization." So it looks to me like the JLS is implying a "best effort" to initialize a class before it is used, but can't absolutely guarantee it in all cases. It would be an interesting experiment to try to write some code to reproduce the case where a ctor is called before its initialization.
