Issue

• The role-based authorization has been enabled inside $JBOSS_HOME/server/$PROFILE/deploy/jboss-brms.war/WEB-INF/components.xml file, like this:

    <!-- SECURITY AUTHORIZATION CONFIGURATION -->
    <!--
        This is used to enable or disable role-based authorization. By default
        it is disabled.
    -->
    <component name="org.jboss.seam.security.roleBasedPermissionResolver">
        <property name="enableRoleBasedAuthorization">true</property>
    </component>

Before making this change, admin user was able to access the tabs like User Permission or Event Log from Administration section of the BRM (i.e. Guvnor) . But, currently it does not even allow admin user to access those features from Administration section , saying Sorry, insufficient permissions to perform this action.
Also, it gives the below ERROR inside server log:
