C0urante commented on pull request #6726: KAFKA-8363: Fix parsing bug for
config providers
URL: https://github.com/apache/kafka/pull/6726
[Jira](https://issues.apache.org/jira/browse/KAFKA-8363)
The regex used to parse config provider syntax can fail to accurately parse
provided configurations when multiple path-less configs are requested (e.g.,
`${provider:pathOne} ${provider:pathTwo}`). This change fixes that parsing and
adds a unit test to prevent regression.
This bug is present since the addition of config providers and so should be
backported through to 2.0, when they were first added.
