OpenJDK uses webrev as the code review tool. The process of creating a code review and handling lies on the shoulders of the AdoptOpenJDK community, which developed a web tool called Betterrev. Review Board along with the Mercurial plugin can be used as well. It automatically generates code reviews, synchronizes with Oracle repository, and performs other useful tasks.
We will need a computer capable of building OpenJDK and which can handle a large amount of code. Also, we will need a development environment installed, as described in Chapter 8, Hacking OpenJDK. We will also need Internet access.
We will create a code review using the Betterrev tool, by following the given steps:
First, let's clone a repository from Bitbucket.
Go to the Betterrev Bitbucket at https://bitbucket.org/adoptopenjdk/betterrev/src:
Fork it, using the highlighted button:
Specify the repository name in the Name field, and add a description if needed.
