    Description

      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.
