I sett up a security role that denied access to: /*/title intending to test if this would deny me access to that property. That worked, I can no longer see titles anywhere. But the log file shows a stack trace and a warning. I looked into the stack trace and found it is printed out in getNodeData on Content. In this method the WARNING worthy unexpected RepositoryException catches the benign and from time to time expected AccessDeniedException as well. Attached find the stack trace as well as a patch that fixes the problem.
