Thank you, Alan

I already pushed it into hotspot/jdk: http://hg.openjdk.java.net/hsx/hotspot-main/jdk/rev/9d5c43050210 We will promote it as we did before with similar changes together with Hotspot changes.

So this seem to be becoming a new process for avoiding flag days - which is not a bad thing. But previously this was only a special exception for jsr-292 and now we seem to be generalizing it without there being any proper discussion to ensure all the right pieces are place to do this and so that everyone knows what is being done.

Thanks, Vladimir

Hi guys,

This is the JDK side of changes for supporting @Contended: http://cr.openjdk.java.net/~shade/8003985/webrev.jdk.02/ Status: - This change is ready to be pushed; due to licensing reasons with jsr166, we can only commit the stub; regular jsr166 sync will bring the updated annotation later. - JEP-142 is in Funded state (http://openjdk.java.net/jeps/142) - CCC is in place, and Approved. I need a sponsor to push this. Looks fine (although I do not like seeing this going into sun.misc). Do you want this to go into in via jdk8/tl? If so I can push it for you today, just let me know. -Alan.
