Hi,
I solved the problem for
"Startup Error: Failed to init sub-manager: Exception loading and instanciating sub-manager: com.sap.caf.km.repositorymanager.CAFSecurityManager (java.lang.reflect.InvocationTargetException: null)"
by changing the Security manager of this repository.
The default entry is CAFSecurityManager - I changed it to ACLSecurityManager.
After that it works without any error messages in component monitor or elsewhere.
regards
Darijo
