JVM Language Summit

July 29–31, 2019
Oracle Auditorium, Santa Clara, California

We are pleased to announce the 2019 JVM Language Summit to be held at Oracle’s Santa Clara campus on July 29–31, 2019.

The JVM Language Summit is an open technical collaboration among language designers, compiler writers, tool builders, runtime engineers, and VM architects. We will share our experiences as creators of both the JVM and programming languages for the JVM. We also welcome non-JVM developers of similar technologies to attend or speak on their runtime, VM, or language of choice.

Presentations will be recorded and made available to the public.

This event is being organized by language and JVM engineers—no marketers involved! So bring your slide rules and be prepared for some seriously geeky discussions.

The Summit will be immediately followed by the OpenJDK Committers’ Workshop, August 1–2. This year, the Workshop is a separate event with its own registration process.




The Summit is held in a single classroom-style room to support direct communication between participants. About 100–120 attendees are expected.

The schedule consists of a single track of traditional presentations interspersed with less formal, multi-track “workshops” and, possibly, impromptu “lightning talks”.

Workshops are open discussion groups with only a small amount of prepared material. We ask each registrant to suggest a few topics of interest. After choosing the most popular topics, we'll ask some registrants if they would like to act as discussion leaders.

Why Should I Attend?


As space allows, we are open for registration at https://openjdk.regfox.com/jvmls2019. Speaker registration ends May 24.

Speakers: If you’d like give a presentation, please register as a General Speaker or Oracle Speaker (the latter for Oracle employees) and include a detailed abstract. There is no fee. See below for help preparing your abstract and talk. You will be notified about whether your proposal has been accepted; if not, you will be able to register as a regular attendee.

Regular attendees: Please register as a General Attendee. To cover costs, we are charging a conference fee of $295. Space is limited; if there are no available slots, send us an email and we'll let you know if we end up with more openings.

Oracle employees: Oracle employees interested in attending (but not speaking) should register as an Oracle Attendee. There is no fee. There may be more interested employees than there is space to accomodate them. Thus, all Oracle registrations are provisional, and you will be notified about approval. In the mean time, you should also get approval to attend from your manager.

Questions? Please send inquiries to inquire2019@jvmlangsummit.com.

All registrants should review the Oracle Event Code of Conduct.
