Was working around calling gs.getProperty in my client callable script include and then use it in a condition builder and came across this property.

Script sandboxing prevents certain functions from being accessed for security purposes. You can validate this by opening scripts background and selecting the 'Execute in sandbox' option. This property cannot be modified also interestingly gs.info and gs.log calls are restricted.
