   ### Question
   - In SW i use TraceCrossThread make trace across thread. But I also want transport my threadLocal variables through threads, here  i make a nest wrapper callable ,like this : 
           Future<List<Users>> operationFuture = pool.submit(CallableWrapper.of(new ThreadLocalCallable(userWrapper::doRecall)));  
   
   when  ThreadLocalCallable construct method was called, i record the  threadLocal variables  ,then   when userWrapper::doRecall was called i set the  threadLocal variables to the work thread context, so in doRecall method it can access the  threadLocal variables.
   
   I want to known ,is there a better way to transport the threadLocal variables in SW? or should another annotation to permit transport  threadLocal variables ?

   I can't see there is the difference between the thing you described and native `TraceCrossThread`. If you are going to change source codes, what makes it better?
