Greetings everyone.
We are experiencing some issues with Validator 2.0.1, which i can't quite figure out on my own.
When attempting to start a Workflow through the UserAppConnector, it throws the following error:
Error while executing action method startWorkflow: java.lang.AssertionError: java.rmi.RemoteException: Premature end of Content-Length delimited message body (expected: 422; received: 0); nested exception is: org.apache.http.ConnectionClosedException: Premature end of Content-Length delimited message body (expected: 422; received: 0)
Looking at UserApp logs, the workflow seems to run as it should, but Validator 2.0.1 still seems to get dropped before it receives the response it is expecting. I don't see any sign of this in the UserApp catalina.out logs.
It seems like workflows are executing without any trouble when i start them directly through the Dashboard.
I suspect it could be caused by the LoadBalancer in front of UserApp misbehaving, but is there any other possible explanation?
