Description

The regex used by the ConfigTransformer class to parse config provider syntax (see KIP-279) is broken and fails when multiple path-less configs are specified. For example: "${provider:configOne} ${provider:configTwo}" would be parsed incorrectly as a reference with a path of "configOne} ${provider".
