ClassNotFoundException happens when putting a custom object with jboss-marshalling in RHDG 8.x embedded module on JBoss EAP

Issue

We installed RHDG 8 embedded modules on JBoss EAP and configiured our application with using jboss-marshalling:

<cache-container name="embedded-container">
    ... 
    <serialization marshaller="org.infinispan.jboss.marshalling.commons.GenericJBossMarshaller">
        <white-list>
            <class>com.example.ExampleObject,com.example.TestObject</class>
            <regex>com.example.*,foo.bar.*</regex>
        </white-list>
    </serialization>
    ... 
</cache-container>

When putting a custom object, it fails with the following ClassNotFoundException. This issue happen even if the custom object com.example.ExampleObject is correctly specified to the <white-list> setting.
