Java, Today and Tomorrow by Mark Reinhold
What’s new in Java today, and what’s coming to Java tomorrow? We’ll start with a review some of the recent additions to the language and the platform. We’ll then look ahead and demonstrate some of the features currently in development in the Amber, Loom, Panama, and Valhalla projects. All of these features will continue to improve both developer productivity and program performance while retaining Java’s core values of readability, generality, and compatibility.

Immutable Collections In Java – Not Now, Not Ever
In JDK terminology, immutable and unmodifiable have shifted over the last few years. At first, the term immutable was used for the collections returned by Java 9’s collection factory methods. But will a method that prints all elements in an immutable collection always have the same output? Yes? No? What’s An Immutable Collection? Is immutability a feature? Can Unmodifiable And Immutable Collections Be Retrofitted? Find out now!

Excursions into Deduplication
For many workloads strings can be the most significant contributor to memory footprint.
When are Strings deduplicated? How can you find out whether they are of any benefit in your application? How much does it cost in terms of CPU?
This article will guide you how to easily find the answers to the questions above.

Box Old Objects to Be Autoclosable
Since Java 7 we can use try-with-resources and have any object automatically closed that implements the Autocloseable interface. But some of the classes need some wrap-up but are not Autocloseable. In this article Peter Verhas is sharing a nice tip how we can close such resources in very simple way! Check it out!

Can instanceof make Unmodifiable Collections faster?
In a battle-hardened code base, all normal bugs were fixed - those that remain are usually quite bizarre. This is a story of one such bug and how it uncovered a less than optimal implementation in the JDK itself.

JEP Draft: Add Detailed Message to NullPointerException Describing What is Null
Programming errors like NullPointerExceptions would rarely go to production, however, they might be really hard to troubleshoot as by default they don't contain a message.
Take a look at this new JEP trying to address this limitation available for years in the JDK.
