Found a manner to do that.

I've added a file jolokia-access.xml in src/main/recsources folder, containing

<filter>
    <mbean>java.*</mbean>
    <mbean>org.*</mbean>
    <mbean>sun.*</mbean>
    <mbean>jdk.*</mbean>
    <mbean>jolokia*</mbean>
    <mbean>JMImplementation*</mbean>
    <mbean>com.sun.*</mbean>
</filter>
