You are using an ESB environment.

Solution

1. Set the following JVM system property on the container where Sonic Connect is deployed:
   -Dorg.apache.cxf.transport.http.async.usePolicy="ALWAYS" 
   
   
2. Add all the JARs from the zip file attached to this article to the Sonic Connect service type classpath.
