Value Types are coming in the next version of Java. Yes, it is great to be able to allocate on the stack, but then Java has better garbage collectors, including a completely pauseless one available commercially. Even in this announcement the new GC mentioned for Go is non generational. I have a feeling that even Java's good old CMS is better. Java also does escape analisys. All in all, once value classes are in, it is going to be awesome.
