Upgrade issue: Related to RestProxyServicePlugin

Hi Team,

I am getting following exception after the upgrade to hippo version 13.00. I think there is some jar version mismatch or missing jar.

java.lang.ClassNotFoundException: org.hippoecm.frontend.service.restproxy.RestProxyServicePlugin
Failed to instantiate plugin class ‘org.hippoecm.frontend.service.restproxy.RestProxyServicePlugin’ for wicket id ‘null’ in plugin
‘home.cluster.cms-static.plugin.servicesLoader.cluster.cms-services.plugin.hstRestProxyService’
(JcrPluginConfig:/hippo:configuration/hippo:frontend/cms/cms-services/hstRestProxyService)

If I remove the plugin.class property of this node(/hippo:configuration/hippo:frontend/cms/cms-services/hstRestProxyService) it will start giving me following exception:

No plugin classname configured, please set plugin configuration parameter plugin.class
Failed to instantiate plugin class ‘null’ for wicket id ‘null’ in plugin
‘home.cluster.cms-static.plugin.servicesLoader.cluster.cms-services.plugin.hstRestProxyService’
(JcrPluginConfig:/hippo:configuration/hippo:frontend/cms/cms-services/hstRestProxyService)

Can you guys give some pointers around it?

Thanks in advance.

Regards,
Priyanka
