Hessian not workin in wildfly 8.2.0

I am deploying an EAR application in Wildfly 8.2.0 in linux machine. Application contains webstart and hessian protocol.

ERROR [io.undertow.request] (default task-23) UT005023: Exception handling request to /hessian/app: java.lang.RuntimeException: 11 is an unknown object type

This happens during deserialization in Hessian protocol. When I checked the logs, I am getting the below exception.

Caused by: java.io.EOFException: readObject: unexpected end of file
at com.caucho.hessian.io.CollectionDeserializer.readLengthList(CollectionDeserializer.java:93)
at com.caucho.hessian.io.UnsafeDeserializer$ObjectFieldDeserializer.deserialize(UnsafeDeserializer.java:417)

Is it related to configuration for wildfly remote access ? Have any one faced this issue ? Please help.
