             Summary: UIMA-DUCC: pullservice should synchronize GET retry when 
client has no tasks to give
                 Key: UIMA-5867
                 URL: https://issues.apache.org/jira/browse/UIMA-5867
             Project: UIMA
          Issue Type: Improvement
          Components: DUCC
            Reporter: Jerry Cwiklik
            Assignee: Jerry Cwiklik
             Fix For: 2.2.3-Ducc


When a client has no more tasks to give, the service should synchronize GET 
retry until the client has more tasks to process. A single thread will keep 
asking for a task while other threads block. When a task becomes available, the 
service should unblock all threads and resume normal processing.
