Nikita Lipsky and Dmitry Chuiko on AOT in Java on jug.msk.ru

The next meeting of the Moscow Java User Group was held on May 22, 2017, traditionally in the office of CROC . Nikita Lipsky and Dmitry Chuiko talked about static (Ahead-of-Time) compilations in the Java programming language and its implementation in Excelsior and Oracle products.



About speakers


Nikita Lipsky represents the Novosibirsk company Excelsior , which produces a unique product - a static compiler for the Java language , Excelsior JET . The application is quite popular and feels great on the market, this fall will mark 20 years of its existence. Nikita is one of the initiators of the creation and an active participant in the development of the application.

The company's blog is quite interesting: in addition to announcements of new versions (with plug-ins for Maven and Gradle ), there is a description of other useful things like the Git-plugin for Far Manager and the plugin for IntelliJ IDEA (written by Excelsior programmers). Judging by the survey , you can soon expect something else.

For familiarization with Excelsior JET, the first one and two first reports are most useful (Nikita's joint presentation with Pavel Pavlov on JUG.ru in 2013), then you can see stories about product technical support .

About reports


For both speakers, the jug.msk.ru meeting was part of a conference tour round. Nikita’s tour began with his participation in the release of the 134 podcast debriefing (from the airport). Next were Riga DevDays 2017 , GeeCON 2017 , jug.msk.ru and Oracle Code 2017 Moscow . Dmitry's tour included also GeeCON 2017 and jug.msk.ru , then JEEConf 2017 .

The meeting and the theme of the meeting ( AOT ) were of great interest. At least five speakers of conferences held by JUG.ru were present as spectators. Those. In total (taking into account Dmitry and Nikita) there was a rare opportunity to see and talk with seven speakers.

Andrei Kogun, together with Nikita (the first picture) and, additionally, Dmitry (the second picture) begins the meeting.



Nikita spoke first. In my opinion, this is the best or one of his best reports. The report lasted two hours, which allowed him to tell more and answer more questions from the audience. The speech greatly interested those present. The questions were good and sometimes unexpected for the speaker (for example, about comparing the launch time of applications on the SSD).



With the release of JDK 9 "out of the box" the possibility of static compilation appears, i.e. conversion to the target platform code (the so-called native ). True, so far only under Linux . O JEP 295 , JEP 243 and the Graal compiler was the story of Dmitry. The report was a logical continuation of his previous report presented earlier at the JUG.ru meeting .



As always, during the break and after the reports, those who wished had the opportunity to communicate and ask questions on topics of concern to them. And, of course, drink tea with buns.
