title: What is in Java object header?
body: <p>Could you give me some information on what is exactly stored in object header? I know, that it's probably JVM dependent, but maybe for HotSpot at least? I'm looking for exact description specifically for a first row.</p>
  
  <p>I've read several information that I can't verify positively with information I find. Maybe you have a link to OpenJDK wiki that says it all?</p>
