[Juglist] synchronization on reassigned field

[Richard O. Hammer]

I've written code something like this:

final static String //process status codes
  JUST_STARTING     = "just starting",
  GETTING_ALONG_NOW = "going okay",
  DONE_BY_GOSH      = "all wrapped up";
String processStatusCode = JUST_STARTING;

...

synchronized(processStatusCode){
  if (processStatusCode == JUST_STARTING){
    //do something
    processStatusCode = GETTING_ALONG_NOW;
  }else if (processStatusCode == GETTING_ALONG_NOW){
    //do something else
    processStatusCode = DONE_BY_GOSH;
  }
}
I think maybe I'm getting myself into trouble here, but I'm not quite 
sure.  If I get a lock on the object assigned to processStatusCode and 
then reassign processStatusCode to point to a different object, where 
does my synchronization stand?

Thanks,
Rich Hammer
