The end of year rush

Update: Numerous JSRs migrate to, Project Nashorn picks up pace

Things show no sign of slowing up for the holidays at Java development central as JSRs and JavaScript project Nashorn make big moves

You’d expect core development at the heart of Java to slow up slightly in December, with thoughts firmly turning to the holiday season.

That doesn’t seem to be the case this year though, as important moves are made within the OpenJDK and the JCP.

In line with the mammoth Java Community Process reform,, it has been announced that several JSRs have migrated to the latest JCP program.

According to Heather VanCura, responsible for running the JCP Program Office, five JSRs have met the new guidelines towards greater transparency

They include:

  • JSR 310, Date and Time API, led by Stephen Colebourne and Michael Nascimento and Oracle (Roger Riggs)  
  • JSR 349, Bean Validation 1.1, led by Red Hat (Emmanuel Bernard)
  • JSR 350, Java State Management, led by Oracle (Mitch Upton)
  • JSR 339, JAX-RS 2.0: The Java API for RESTful Web Services, led by Oracle (Santiago Pericas-Geertsen and Marek Potociar)
  • JSR 347, Data Grids for the Java Platform, led by Red Hat (Manik Surtani)

All five are particularly important for upcoming Java releases so it’s nice to see them fall in line officially with the new structure. Hopefully this will spur others on to make the same move.

Elsewhere, plans to renovate the JavaScript JVM engine in Project Nashorn have been approved in the OpenJDK vote.

On the Nashorn blog, Jim Laskey said he had a busy week ahead, after this email from HotSpot Group Lead John Coomes:

Voting on the Nashorn Project with initial Lead Jim Laskey [1] is closed.

Yes:  20

Veto:  0

Abstain:  0

According to the Bylaws definition of Lazy Consensus, this is sufficient to approve the new Project and its initial Lead.

With everyone in favour of Nashorn, and it being led by Laskey, work can now begin in getting Rhino’s successor ready in time for Java 8 in September 2013. There’s plenty excitement about the project that aims to embed JavaScript into Java applications, with the veil lifted in late November. Although information is still on the sketchy side, we’re eager to hear about the compatibility with node.js and how the node.jar will feature.

This recent news means we should find out more information in due course, with the green light now properly given to Nashorn. Oracle do not appear to be shirking their responsibilities with Java, even with a vacation in sight, which is good to see.
