Apache Directory Server
ApacheDS is an extensible and embeddable directory server entirely written in Java, which has been certified LDAPv3 compatible by the Open Group.

It has been designed to introduce triggers, stored procedures, queues and views to the world of LDAP which has lacked these rich constructs.
Gerrit Code Review System
Gerrit is a Web-based code review tool built on top of the Git version control system. Changes are uploaded to Gerrit but don’t actually become a part of the project until they’ve been reviewed and accepted. Gerrit supports the standard open source process of submitting patches which are then reviewed by project members before being applied to the code base.
It’s an open source continuous integration tool written in Java. Jenkins provides continuous integration services for software development. It is a server-based system running in a servlet container such as Apache Tomcat. The official Jenkins Docker is used in conjunction with additional plugins and scripts in order to integrate with Gerrit.
