Description

I tried to Invoke a simple echo service using Axis2 Mail transport. Request message went into the service properly and the service returns the response value. So the "In" path is OK. But on the out path, I get the following exception on the client side.

org.apache.axiom.om.OMException: com.ctc.wstx.exc.WstxEOFException: Unexpected EOF in prolog

So I did some investigation on this issue. When I log into the gmail mail account that I've used in this sample, the request and response messages are correct. But when I build the client side input stream (for the response message), it shows as follows.

<?xml version=3D'1.0' encoding=3D'UTF-8'?><soapenv:Envelope xmlns:soapenv=
=3D"http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Header xmlns:wsa=3D=
"http://www.w3.org/2005/08/addressing"><wsa:Action>urn:echoResponse</wsa:Ac=
tion><wsa:RelatesTo>urn:uuid:71bddf37-73ba-42f0-bae2-7de4738ccac8</wsa:Rela=
tesTo></soapenv:Header><soapenv:Body><ns:echoResponse xmlns:ns=3D"http://se=
rvice.sample.mail.wso2.org"><ns:return>Helloo...</ns:return></ns:echoRespon=
se></soapenv:Body></soapenv:Envelope>

The message is broken into lines and there are additional characters added at the end of each line. But I couldn't find out why this happens. Same MailTransportSender and MailTransportListener codes are used in both client and server sides. But this happens only on response path.

I'll attach everything needed to reproduce this issue.

Thanks,
