Date and Time API makes it into Java 8
JSR-310 spec lead Stephen Colebourne says that inclusion is a major step for the project.
Java Date and Time API,
led by Joda-Time creator Stephen Colebourne, has made it into JDK
8. The inclusion is an important step towards public release as
part of Java SE 8, which is due later this year.
JSR-310 (or ‘ThreeTen’ as the project is known internally) is designed to replace the existing Date and Calendar classes, incorporating ideas from Colebourne’s Joda-Time. It has become one of the most anticipated features of Java SE 8, especially after the delay of modularisation project ‘Jigsaw’.
On the public ThreeTen mailing list, Colebourne wrote that it was a “major step for the project”. He later told JAXenter by email: “The integration happened in two steps. The first included a complete set of functionality but still with some real work to do, the second, which [was] completed last Friday helped complete the remaining rough edges.”
That’s not to say that the hard work is over. “From now on, the effort is on bug fixes, tightening the Javadoc/spec and testing, rather than features or design changes,” he added.
The ThreeTen site provides reference documentation to supplement the standard JavaDoc and a backport to JDK 1.7 (albeit with a disclaimer stressing that it is “NOT an official implementation”).
Colebourne is an outspoken critic of the JCP, the democratic organisation involved in overseeing the development of the Java platform. He described it to JAXenter as “kind of a fake zombie body”, despite recent efforts taken by the likes of the London Java Community to push reform through.
In the same interview, he warned that “JSR-310 aims for JDK 8,” adding that it is “up to a whole variety of people to decide on whether they want to accept it or not”. With the API now available in future JDK 8 milestone builds, it appears his pessimism was unfounded.
