Broker Camel component throws an error "java.lang.IllegalStateException: Not the original message from the broker Message"

Issue

I have a simple camel route using broker camel component:

<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring">
    <route id="brokerCamelTest">
        <from uri="file:data/input" />
        <convertBodyTo type="java.lang.String" />
        <to uri="broker:queue:output" />
    </route>
</camelContext>

When I tried to copy a file contains a simple string "this is a test" over to "data/input" folder, I was getting following error from Camel:

java.lang.IllegalStateException: Not the original message from the broker Message: this is a test
