[jira] [Created] (POLYGENE-224) Initialization race condition in ServiceReferenceInstance

Lukas Krecan created POLYGENE-224:
-------------------------------------

             Summary: Initialization race condition in ServiceReferenceInstance
                 Key: POLYGENE-224
                 URL: https://issues.apache.org/jira/browse/POLYGENE-224
             Project: Polygene
          Issue Type: Bug
            Reporter: Lukas Krecan


When multiple threads want to use ServiceReferenceInstance there is an activation race condition.

Instance is set by first thread [here|https://github.com/apache/polygene-java/blob/develop/core/runtime/src/main/java/org/apache/polygene/runtime/service/ServiceReferenceInstance.java#L152] but the initialization (activation) is not finished yet. Since the instance variable is already set, other threads can obtain and use uninitialized instance.
