laid out the roadmap for Java 9, which could mean better modularity and new value types. Improved modularity could reduce app size and improve startup performance. New value types will make it easier ...

Is it just the size of the object instance you’re examining ... Memory alignment does matter (as shown, for example, for primitive array types in Java Tip 130), but I think it is unprofitable ...
