Getting benefits from the AdoptOpenJDK project

AdoptOpenJDK is a program, initially developed by a small group of enthusiasts, but which became part of an official OpenJDK community. Some of the purposes are to clarify and simplify OpenJDK building, installation, and usage, but there is still more. It provides build automation, a report generator, build testing, and more. We will cover some basic features that will be useful for everyone.

Getting ready

To follow this recipe, we will need an OpenJDK instance installed, and an Internet connection established.

How to do it...

AdoptOpenJDK is a very helpful and a very sophisticated project set with quite a few different subprojects. Many of them concern testing and evangelism, so we could not include them here as recipes.

Visualizing JIT logs

There is a project named Jitwatch in AdoptOpenJDK. Its purpose is to visualize JIT compiler logs. It helps to find some of our project's performance deficiencies and inspect a native assembly output, as it's...
