I don't know if there's anything built in, but you could always make 
everything derive from:

class DebugObject extends Object //    NOT checked for syntax!
{
   private  static   int   objectCount = 0;

   DebugObject ()
   {
      super();
      ++objectCount;
   }

   protected void finalize()
   {
      objectCount--;
      super.finalize();
   }

   public   int   objectCount()
   {
      return (objectCount);
   }
}


If you want to simplify switching back & forth, you can also have:

class JavaObject  extends Object
{
   JavaObject()
   {
      super();
   }
}


Then it's pretty simple to do replace-all in your project.  (If you 
replace-all to "Object", it can get trickier to go back to DebugObject, 
depending on the rest of your project.)

If *ONLY* javac had a preprocessor!  ;)
