All of the inputs have been that java 7 is NOT getting closures.
It seems however closures will now be in java 7:
Does anyone have any other information or insight to this possibility? Can anyone furthermore confirm or deny the state of closures?
Artima has a good summary of the current (Dec 2009) situation.
One year ago, Mark Reinhold, Principal Engineer at Sun Microsystems, announced At the Devoxx conference in Antwerp, Belgium that the next major release of Java, JDK 7, would not include closures. At the same conference this year, however, Reinhold announced in a surprise turn around the Java would be getting closures after all in JDK 7
Thats from infoq about it (Dec 19).
Closures will be on JAVA 7 and the JDK 7 schedule will be extended until around September 2010
