Yasson and EclipseLink go to EE4J

I am happy to announce that we are planning to transfer Yasson and EclipseLink projects to EE4J. These will be one of the first projects transferred because they are a part of Eclipse Foundation already. I already posted announcement in EE4J community mailing list here:

https://dev.eclipse.org/mhonarc/lists/ee4j-community/msg00341.html

The transfer will not affect any committer rights, but it may introduce some changes in web site URL, mailing lists, etc.
I’ll keep you updated about the progress.

Introducing Yasson

I am glad to inform you JSON-B RI and EclipseLink projects have been successfully separated. It was not a union of heart, but more marriage of convenience. Both projects had the same committers. Therefore, JSON-B RI was started in a directory inside EclipseLink project. But when JSON-B RI project started to be more and more mature we started to realize that the idea of hosting it inside EclipseLink project was not so good. These projects have different release cycles and different committers. Currently all JSON-B RI committers are EclipseLink committers, but not vice versa. Also, it can change in future, when more JSONB-RI committers are added.

Java2days 2016

Here are slides from my sessions on java2days conference in Sofia (Bulgaria) which I’ve done together with Werner Keil. I would like to say thanks to all people who attended my talks. Your questions were smart and your ideas were constructive.

As bonus here is a link to a small photo album with night pictures of Sofia I took during my stay there.
