OpenJDK Committers’ Workshop

OpenJDK Committers and other regular contributors traditionally meet each February, in the Free Java devroom at FOSDEM in Brussels. The Free Java room runs for just one day, however, so there’s not a lot of time for the focused discussions amongst OpenJDK contributors that many of us enjoyed at the first Workshop in Santa Clara, California last August.

We therefore plan to hold a one-day OpenJDK Committers’ Workshop on Monday, 4 February, the day after FOSDEM. This time there won’t be any prepared presentations, since presumably those will have been presented during FOSDEM. We’ll instead run the entire day as an unconference, with plenty of time to discuss both technical and community issues.

The workshop will be held at Oracle’s office in Vilvoorde, Belgium. Vilvoorde is about 6 miles (10 km) from central Brussels, and reachable from there by both car and mass transit. For those traveling by car, there is ample on-street parking surrounding the venue on Koning Boudewijnlaan and Medialaan, and on other adjacent streets.

There will be no fee to attend but space will be limited, due to the size of the venue, so we ask that you register in advance. As at the first Workshop, preference will be given to Committers with a strong record of past contributions, though some space will be made for new Committers who have a strong potential for ongoing future contributions.

We’ll start at 10am and finish by 6pm. Food will not be provided, but there are restaurants nearby for lunch.


To register, send a short e-mail message to with a brief summary of your past contributions in the OpenJDK Community and also your full name, employer (if any), and mobile phone number. This information will be used for registration purposes only and will not be shared outside of Oracle. You should receive a reply within 48 hours.

Due to the security policy of the venue, if you do not register in advance then you will not be admitted to the building.


The Workshop will be organized entirely as an unconference.

Sessions will be of two possible lengths, short (20–30 minutes) and long (45–60m); we’ll determine the exact length once we see how many proposals are made.

The very first unconference session will be devoted to deciding the agenda for the rest of the unconference. Additional session proposals may be made at that time.

The unconference sessions will not be recorded.

To help organize things at least a little bit in advance, we’re collecting both proposals for specific sessions and suggestions of specific topics.

If you’d like to lead a session on a specific topic, please send a message to the workshop-discuss list with a subject line that starts with “Workshop proposal:”. Include a clearly-marked title, abstract, length (short or long), brief biography (or link to same), and blog and microblog links if relevant.

A session may include a prepared presentation, or it may just be free-form discussion, or anything in between—it’s all up to you and those who show up. If you start with a prepared presentation, though, please make sure to leave ample time for questions and discussion.

If there’s a topic that you’d like to discuss, or just hear more about, but you’re not willing lead a session on it, then please send a note describing the topic to the workshop-discuss list with a subject line that starts with “Workshop topic:”. Give your topic a name, describe it, and be sure to include one or more questions that you’d expect session participants to address. Such expressions of interest could motivate other people to propose relevant sessions.
