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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
