Code Tools Project

The goal of this Project is to provide tools of use to developers who work on the OpenJDK code base. Such tools currently include test tools and VCS extensions; it is envisaged that additional tools will be added over time, after discussion on the Project's main mailing list and subject to the Project Lead's approval.

This Project is sponsored by the Compiler Group.
