Congratulations to Torsten and Stephan for their implementation of continuations for java!

Their work is available in the Cocoon CVS as the javaflow block, but my guess is that it could be of interest to other projects as well.

If you want to know what continuations are and what they're used for, have a look a the Cocoon Flow documentation.

Update: although this might sound too good to be true it is not an April's fools joke, you can actually check it out!
