CamelRestletResponse=HTTP/1.1 - Internal Server Error (500) - The server encountered an unexpected condition which prevented it from fulfilling the request

The customer is facing the below issue for some time while connecting with ESB Backend URLs using the Restlet component.

ISSUE:
======

• Some time while connecting with ESB Backend URLs using Restlet components. They have exposed their services using Restlet components. As soon as the Camel Restlet component receives a request, some extra header gets automatically created. below are the headers getting created automatically

• CamelRestletResponse=HTTP/1.1 - Internal Server Error (500) - The server encountered an unexpected condition that prevented it from fulfilling the request

• CamelRestletResponse=HTTP/1.1 - Request Timeout (408) - The client did not produce a request within the time that the server was prepared to wait

• Whenever they are getting these headers they are not able to connect with BackendAdapter. Their Backend service is also exposed using the Restlet component.

• They are getting the below error:
• org.apache.camel.component.restlet.RestletOperationException: Restlet operation failed invoking http://jocatabackendadapter.prod.svc.cluster.local:9902/rest/jocata/v1.0/fetchOfferDetails with statusCode: 1001 /n responseBody:HTTP/1.1 - Communication Error (1001) - The connector failed to complete the communication with the server at org.apache.camel.component.restlet.RestletProducer.populateRestletProducerException(RestletProducer.java:305)

• As per the customer, when this header is set to any value other than 200, calling the backend adapter fails with either of the following errors:
  i) Communication Error (1001) - Need to check under what scenario this error is generated
  ii) Socket timeout error: This is because of the network issue the communication with the backend system got timed out
  ii) Connect to 172.16.32.68:8081 [/172.16.32.68] failed: Connection refused (Connection refused) - Either the backend server is not running or the backend server is not able to accept the connection. Asked them to check if the host is reachable using telnet.
