There have been several recent developments in the Java-sphere this week and I summarize some of them in this post.
The End of JavaOne as We Know It
In the post “JavaOne Event Expands with More Tracks, Languages and Communities – and New Name,” Stephen Chin writes, “The JavaOne conference is expanding to create a new, bigger event that’s inclusive to more languages, technologies and developer communities.” He adds that it has been renamed to “Oracle Code One” and that this year’s edition (the “inaugural year of Oracle Code One”) will be held in San Francisco’s Moscone West in late October (October 22-25, 2018).

Mission Control Project in OpenJDK
Marcus Hirt has proposed “the creation of the Mission Control Project” on the OpenJDK announce mailing list. This seems like a logical step in the effort discussed in Mark Reinhold‘s message “Accelerating the JDK release cadence” to “open-source the commercial features in order to make the OpenJDK builds more attractive to developers and to reduce the differences between those builds and the Oracle JDK” with the “ultimate goal” of making “OpenJDK and Oracle JDK builds completely interchangeable.”
Flight Recorder in OpenJDK
Speaking of commercial features of the Oracle JDK being brought into the OpenJDK, JEP 328 (“Flight Recorder”) had some interesting news this month with Markus Gronlund’s hotspot-dev mailing list announcement of the availability of “a preview of a large part of the source code for JEP 328 : Flight Recorder.”

Significant Progress on Switch Expressions (and Improving Switch Statements)
There has been significant progress in the OpenJDK mailing lists’ high-level design of
switch expressions that includes enhancements to the existing
switch statements since my original post on switch expressions. I have summarized some of the latest discussion (particularly that in a Brian Goetz post) in a recent blog post called “Enhancing Java switch Statement with Introduction of switch Expression.”
Should I Return A Collection or Stream?
There’s an interesting thread “Should I return a Collection or a Stream?” on the Java sub-reddit that is based on an interesting July 2017 discussion on StackOverflow related to whether it’s most appropriate to return a
Collection or a
Stream in a particular case.
