      Description

      The LRA spec supports starting LRA's via a Java API or via Java annotations. If the two approaches are used together in the same resource method then the LRA started via the API should be nested inside the one started by an annotation.

      If the annotated class also contains @Compensate and @Complete annotations (which means that the resource should join the outer LRA) and the resource method Joins the nested LRA then the resource should receive callbacks for both the outer and nested LRA's.

      The following code shows an example:

          @PUT
          @LRA(LRA.Type.REQUIRES_NEW) // starts a new LRA on entry
          public String doInTransaction() {
              URL lraId = lraClient.startLRA(...); // starts a nested LRA
      
              lraClient.join(...) // join the nested LRA
      
              lraClient.closeLRA(lraId); // close the nested LRA
              // assert that the nested callbacks were invoked
              // assert that the callbacks for the outer LRA have not been called yet
          }
      

      Similar comments apply if the resource joins via the LRAManagement API:

          @Inject
          private LRAManagement lraManagement;
      
          public String doInTransaction() {
              lraManagement.joinLRA(this, lraId, 0L, TimeUnit.SECONDS);
              // etc
