Java Magazine March/April 2016 is an interesting issue as it focuses on Java and the Java Virtual Machine. This is essentially the "core" of the Java Platform.

It consists of the following main topics:

1. The new garbage collectors (G1 and Shenandoah) in OpenJDK. 
2. Understanding what the JIT is doing. 
3. Understanding the Java Hotspot VM Code Cache.
4. How to add lazy operations to collections in order to make them faster and have reduced memory usage. 
5. Explanation of how annotations work under the hood. 
6.  Using enums and how to make the most of them. 
7. A look at The Criteria API which is new in JPA. 
8. Tutorial on Golo - a fast, low-ceremony, and easy-to-learn JVM language. 
9. Overview of Oracle Cloud Services for Java Developers. 
10. A look at the JEP 283 and JEP 263 proposals of interest. 
11. A proposal for new reserved words that will cut boilerplate code e.g. var
12. And of course the usual features on books, letters to the editor, and events to not miss out on.
