I found this page stating that Java 8 support for Juno is deffered, but I can't find more information how soon people can exspect to be able to write first closures in Eclipse and get productive with that stuff.
Has someone got insight how long we still have to wait? The Java7 features were in 3.7 really quickly, that's why it's kind of odd that this task is deferred.
Any comments, ideas? Or maybe even a good workaround?
One of the key reasons that Java 8 support was deferred is that Java 8 will be available after Eclipse Juno is released. A major release of Eclipse couldn't be shipped with functionality reliant on an unfinished Java release.
Java 7 support went through a similar issue with Eclipse Indigo. Tooling for Java 7 proceeded in a branch that was merged into main indigo stream after Java 7 shipped, so you saw tooling support in Indigo SR1.
I would expect a similar situation for Java 8. There may be a branch open for this work already. The best place to check in on the status is in the bug that is referenced from the document that you found.
Java 8 will be released at some point after mid 2013, so there is still quite some time to go :-) Full support in Eclipse for Java 8 should not be expected before Java 8's release date, it was the same for Java 7 support.
Currently, there is no branch open for this work. However, whenever that does happen you can expect to see a few blog posts about it :-)
You may give IntelliJ Idea a try which has preliminary suport for it, see http://confluence.jetbrains.com/display/IDEADEV/IDEA+12+EAP
