Issue on maven-bundle-plugin on export osgi service with property on blueprint

[Ge@@ru]

Hi,

i don't know if this is an issue or is correct.

When it is create an osgi bundle with blueprint and service use property
like this example: 

<blueprint
    xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";

xmlns:cm="http://aries.apache.org/blueprint/xmlns/blueprint-cm/v1.0.0";
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

xmlns:ext="http://aries.apache.org/blueprint/xmlns/blueprint-ext/v1.2.0";
default-availability="optional">
    <!--
    xsi:schemaLocation="
      http://www.osgi.org/xmlns/blueprint/v1.0.0
      http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd";>
      -->

      <service ref="helloservice"
interface="it.test.helloword.HelloWord" >
        <service-properties>
          <entry key="version">
            <value type="java.lang.String">2</value>
          </entry>
        </service-properties>
      </service>

      <bean id="helloservice" class="it.test.HelloWordImpl"
init-method="startUp">
      </bean>
</blueprint>

On manifest property value isn't visible:

Export-Service: it.test.helloword.HelloWord;version=""

Is correct that value isn' present ? 

However, service and use of the properties are correct, all works fine.

Thanks in advance.
