Problem when reading zip files in camel route builder with switchyard

Issue

I am trying to use the Camel ZipSplitter to unzip a zip file and process each file individually. However when trying to do this I get an exception when unzipping the file:

Caught exception of type org.switchyard.HandlerException with message: org.apache.camel.RuntimeCamelException: java.io.EOFException

I am using a file binding in the switchyard project to read the input files:

    <sca:service name="Inbound" promote="Component/Inbound">
      <sca:interface.java interface="com.example.switchyard.switchyard_zip_test.Inbound"></sca:interface>
      <file:binding.file name="file1">
        <file:directory>/tmp/input</file:directory>
        <file:consume>
          <file:move>/tmp/archive</file:move>
          <file:moveFailed>/tmp/error</file:moveFailed>
        </file:consume>
      </file:binding.file>
    </sca:service>

and a Camel component to process the file:

    <sca:component name="Component">
      <camel:implementation.camel>
        <camel:java class="com.example.switchyard.switchyard_zip_test.Route"></camel:java>
      </camel:implementation.camel>
      <sca:reference name="Outbound">
        <sca:interface.java interface="com.example.switchyard.switchyard_zip_test.Outbound"></sca:interface>
      </sca:reference>
      <sca:service name="Inbound">
        <sca:interface.java interface="com.example.switchyard.switchyard_zip_test.Inbound"></sca:interface>
      </sca:service>
    </sca:component>

The com.example.switchyard.switchyard_zip_test.Route class sets up the Camel definition including Camel ZipSplitter to process the input file:

    public void configure() {
        from("switchyard://Inbound")
            .process(unzipProcessor)
            .log("Received message for 'Inbound'")
            .split(new ZipSplitter()).streaming()
                .log("Trying to send message to 'Outbound'")
                .to("switchyard://Outbound")
                .log("Message sent to 'Outbound'");
    }

Why is the ZipSplitter failing to process the zip file?
