If you need additional dependencies in your provider please deploy it as a
module, see docs and examples on how to do that. For the missing class
you're module definition would need to include:

...
    <dependencies>
    <module name="sun.jdk" export="true" >
        <imports>
            <include path="sun/misc/Unsafe" />
        </imports>
    </module>
    </dependencies>
...
