java.net.SocketException:Unexpected end of file from the server [but this message comes only with one particular user login

Question

We have a client server application which runs using spring remoting framework and we are using jetty server and Java 1.7. We deliver both client and server to the customers.

At one of customer's office, for one of the user login, he is getting this Exception which is mentioned in the title of the postjava.net.SocketException:Unexpected end of file from the server. He is actually doing the search for something which makes a server call and finally he ends up getting this error in the error log.

The weird thing is, nobody else in the Customer's office gets this error. It is very weird.

And also i googled about this exception but did not get appropriate answer.

Please provide your suggestions.

Additionally, if you can share some code snippet or stack trace we can share more realistic comments on this issue. Maybe it is caused by some security options of the client facing this issue.

Are all customers configuration the same?
