SAXParseException when using Mediation Router 1.4.3.0

We have a really simple use case that works fine on MR 1.4.1 and 1.4.2, but throws an exception on 1.4.3.

The exception is:

SEVERE: Failed delivery for exchangeId: ID-S206035J4463581/3455-1222349716850/0-0. On delivery attempt: 1 caught: org.apache.camel.RuntimeCamelException: org.xml.sax.SAXParseException: Premature end of file.
org.apache.camel.RuntimeCamelException: org.xml.sax.SAXParseException: Premature end of file.

It seems to be a problem with using the same stream for the second time.

In order to run the test case:

build both projects using Maven
run tests.camel.CamelApplication from camel-fuse-testcase
run com.sabre.camel.HttpClient from camel-http-client
observe an exception in the CamelApplication console

If you change Camel version in camel-fuse-testcase to 1.4.2.0 (pom.xml), it works fine.
