To follow this recipe, you will need an OpenJDK instance installed and an established Internet connection. The recipe is more for the initial understanding of the process rather than for practical use, so if you are familiar with these matters, don't hesitate to skip this recipe entirely.

We will see what OpenJDK consists of:

There's not very much to see, because there is only the basic on-boarding information. Most of the project business is in the bug tracker.

After we read the information about the project on an official site, we will go to JDK JIRA to see what's happening here. We will go to the JDK9 part of JIRA at https://bugs.openjdk.java.net/browse/JDK/fixforversion/14949.

Here we can see various issues related directly to JDK9 and see how the process is going.

Groups are sets of developers who may work on different projects but in one large scope. Developers participate in chosen projects, and projects are sponsored by groups.

There are four major types of projects:

For example, the JDK9 project is a featured one. The graphics rasterizer project is a replacement one, while the Swing group is a whole group that is focused on the improvement of Swing.

Various ports' projects are obviously the portability ones.
