IDM R12.6 SP8.
The root cause of the RoleDefGenerator NPE is because Account Container class named as "eTDYNAccountContainer" was missing and expected into the metadata definitions. 
Add the container named as "Account Container" and dealing with "User Account" contained class. 
Deploy the new metadata. 
At this stage it should still fail because the metadata item name is generated with "eTDYNContainer001" when "eTDYNAccountContainer" is expected. 
So edit the metadata, change the class name from "eTDYNContainer001" to "eTDYNAccountContainer" and save it.
