Often it is not that simple to change JVM, especially if your application is very fine tuned for a specific GC. In such case, is it always worth to spend hundreds of work hours for migration (and testing it afterwards)? Other aspect is the technical support or other legal/contract bindings.
Besides, I wasn't asking for "magic compiler optimizations". I would prefer to use intrinsics directly. Is there a way to do that in Java?

Of course all of this is JVM specific and each one has its own set.
