    Product prod = new Product();
    prod.setName("PS4");

Answer 1

Here the problem is with multiple rest service implementations i.e., one is jboss rest implementation and another one is jersey.So here in this case , you may have to exclude the jaxrs of jboss by creating jboss-deployment-structure.xml file and excluding that.

Example of jboss-deployment-structure.xml 

    <jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
        <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
        <deployment>
            <dependencies>
                <module name="org.jboss.as.jpa"/>
                <module name="org.hibernate"/>

            </dependencies>
            <exclude-subsystems>
                <subsystem name="jaxrs" />

            </exclude-subsystems>
            <exclusions>
                <!-- <module name="org.jboss.as.jsf"/> -->
                <module name="org.jboss.as.jaxrs"/>
                <module name="com.fasterxml.jackson.jaxrs.jackson-jaxrs-json-provider"/>
                <module name="com.fasterxml.jackson.core.jackson-annotations"/>
                <module name="com.fasterxml.jackson.core.jackson-databind"/>
                <module name="com.fasterxml.jackson.core.jackson-core"/>

            </exclusions>
        </deployment>
    </jboss-deployment-structure>
