> When a configuration value is set to its unresolved expression string, it leads to recursive substitution attempts in {{Configuration.substituteVars(String)}} method until the max substitution check kicks in and raises an IllegalStateException indicating that the substitution depth is too large. For example, the configuration key "{{foobar}}" with a value set to "{{$\{foobar\}}}" will cause this behavior. 
> While this is not a usual use case, it can happen in build environments where a property value is not specified and yet being passed into the test mechanism leading to failures due to this limitation.
