We are migrating from Liferay 6.1 to 7.1. After migration, we are getting "Portlet is temporarily unavailable". However, one more portlet deployed in the same application is working as expected. Exception Track as follows
java.lang.NullPointerException

Hi Prabakar,
it seems it's failing here:https://github.com/liferay/liferay-portal/blob/7.1.x/portal-kernel/src/com/liferay/portal/kernel/portlet/bridges/mvc/MVCPortlet.java#L281

because _renderMVCCommandCache has been initialized, maybe the init method hasn't been called, can you verify why in this case the init method is not called?
Cheers.
