In this month’s Java roundup, we have eight ways to become more familiar with Java 8 for beginners to experts.
Project Jigsaw – Jigsaw development is now full steam ahead, planned in four separate phases. The first three will modularize the JDK, and the last phase will introduce a concrete module system – modules are basically collections of types with associated metadata and resources. Mark Reinhold has also released a draft outlining the project’s updated goals and requirements. Get involved in the discussion today!

A Closer Look at Android RunTime (ART) in Android L – Since an early debut under KitKat and prior to launching in “L”, Java’s newest virtual machine has been put through its paces, and the results are in! Andrei Frumusanu from AnandTech brings us the state of the ART in rendering benchmarks, garbage collection and more.
Groovy on Android – Finally, it is now possible to run Groovy directly on Android! Cédric Champeau, software engineer at Pivotal describes some of the difficulties in building Groovy language support for Android, whose work was recently merged into Groovy.
RoboVM 0.0.14 has been released – RoboVM 0.0.14 updates support for iOS 8 and CocoaTouch, now bundled with Android 4.4.3 runtime libraries.
ByteBuddy – ByteBuddy is an instrumentation library for programmatically generating Java bytecode during runtime, from open source enthusiast and IntelliJ IDEA user Rafael Winterhalter. As well as contributing to DZone and StackOverflow, he also writes an excellent blog, My daily Java.
deeplearning4j – The release of DL4J helps circulate years of research that has, until recently, only been accessible to academia and large corporations. Thanks to Skymind, now you too can leverage cutting edge machine learning techniques to build more intelligent applications.
FlatBuffers – FlatBuffers is a cross-platform serialization library for reading and writing data across high performance applications. It is basically a much slimmer version of Protocol Buffers, without a parsing/unpacking step.
AeroSpike – AeroSpike is an in-memory database solution competing with the likes of SAP HANA, Oracle TimesTen, IBM SolidDB and plenty of others. Last month, AeroSpike joined VoltDB in releasing their platform to the open source community.
Testing With Spock – Given Spock is a behavioral testing framework in Groovy, when you a write a new test in Spock, then it should look something like this sentence. If you’re new to BDD or Groovy, Łukasz Janicki writes an excellent primer for getting started with plenty of sample tests.
Lambda Behave – Think that behavior and tests should always be written in the same language? Lambda Behave might be right for you. While somewhat more verbose, Lambda Behave provides a fluent API wiring your tests and integrating with JUnit.
Testing with Aliens; How to test a JPA type converter with Arquillian – Arquillian is a JBoss project for making testing more portable across IDEs, build tools and servers. It provides a provides a component model for writing integration tests that can be run inside almost any application server or container implementation.
XRebel 1.0 – ZeroTurnaround releases XRebel, the interactive Java profiler.
YourKit 2014 EAP – Six months into their EAP, YourKit has developed several new profiling features, including exact line-level traces, duplicate & highly referenced object detection, performance improvements and better alignment with Java 8.
An ultra-lightweight high-precision logger for OpenJDK – Andrew Haley from the OpenJDK Project documents implementing a flyweight logger in C through the JNI.
Hotspot compile command annotations – There is a good chance you’ll never need to force an inline method in Java thanks to JVM optimizations. If you do, make sure it’s short, make sure it’s hot, make sure it’s well-tested, cf. Fixing the Inlining “Problem”.
Java Method Logging with AOP and Annotations – Yegor Bugayenko walks us through a classic AOP activity, logging, with AspectJ and jcabi-aspects.
