Camel-Dozer Custom Mapping Leads Deployment Failure on Karaf Runtime

Issue

As explained in the official document, this is a sample mapping file for camel-dozer, but can not deploy to the karaf runtime.

<mappings xmlns="http://dozermapper.github.io/schema/bean-mapping"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://dozermapper.github.io/schema/bean-mapping http://dozermapper.github.io/schema/bean-mapping.xsd">
  <configuration>
    <variables>
      <variable name="CUST_ID">ACME-SALES</variable>
    </variables>
  </configuration>
  <mapping>
    <class-a>org.apache.camel.component.dozer.VariableMapper</class-a>
    <class-b>org.example.Order</class-b>
    <field custom-converter-id="_variableMapping" custom-converter-param="${CUST_ID}">
      <a>literal</a>
      <b>custId</b>
    </field>
  </mapping>
</mappings>

Error log is something like this:

Caused by: com.github.dozermapper.core.MappingException: java.lang.ClassNotFoundException: org.apache.camel.component.dozer.VariableMapper from bundle 299 (demo)
