Hello core libs developers! I am Ivan from the Bulgarian Java User Group. We are adopting OpenJDK for quite some time in our JUG. So far we have done some sessions in our community as well as on conferences in Bulgaria and neighboring countries, where we just talked about the project and the adoption topic. We also did some hackathons, where we showed the people how they can download, build, change and use the changed images of the latest version of OpenJDK. On the last Java2Days conference in Sofia we even went further and together with Mani Sarkar from LJC we did Jigsaw project hands on lab, where besides explaining the roadmap and JEPs for the modularity, we built and ran JBoss Forge with the image that we built from the latest source from jigsaw/m2 repository!
And now we decided that we want to go one step further. We think that we are ready for our first real contribution to OpenJDK. Of course, we want to start small, we don't plan to implement project Valhalla in a day ;) We took our time and analyzed the open issues that we found in the OpenJDK JIRA. We selected a few items and before picking one for our hackathon on 11th December, we decided to ask for your opinion. So, this is what we found appropriate: https://bugs.openjdk.java.net/browse/JDK-5050783 *Throwable convenience method: String getStackTraceString()* This stays open for quite some time. Maybe we could add a default method to java.lang.Throwable or static convenience method to another class? https://bugs.openjdk.java.net/browse/JDK-6201180 *(coll) Generics and collections support for generic arrays* We believe that this issue was reported ahead of its time :). It basically proposes adding new methods to the Collection interface, but the proposal came in 2004! Now with default methods it is finally possible. We would argue as well with the syntax: instead of addAll(<? extends E>[] array), we would propose to have addAll(E... array) method (the same applies for the other three proposed new methods as well). https://bugs.openjdk.java.net/browse/JDK-4974893 *(ch) Retrofit scatter/gather interfaces with varargs where possible* I guess we need to discuss this more. Especially the comment "I think this job must be generalized to the whole API." We know that Joe Darcy and the team already ran some effort on cleaning up things like that, but if you still know about generifying/varargsifying/coinifying/labdaifying (wow! :)) internal APIs, we would be more than happy to help. We that, I would conclude the list. Do you think that we can work on one of these next Thursday? If not, what else would you propose? We really hope that we'll be able to do such hackathons once per two months at least. And our next goals is to participate in Jigsaw once it gets to its final straight! Thanks and regards, Ivan
