>                 URL: https://issues.apache.org/jira/browse/LOG4J2-3470
>             Project: Log4j 2
>          Issue Type: Bug
>    Affects Versions: 2.17.2
>         Environment: Running with / in:
> * Spring Boot 2.6.6
> * log4j 2.17.2
> * Docker / K8s on Amazon EKS
> * Java 11
>            Reporter: Jan Mosig
>            Priority: Major

> In our logging submodule we are using log4j2 properties with value expressions to do things, e. g.
> {code}
> <Property name="thing:Environment" value="${env:ENVIRONMENT}" />
> <Property name="thing:Instance" value="${env:HOSTNAME}" />
> {code}
> However, since we upgraded to 2.17.2, the expressions are not (always) expanded anymore, i. e. the log will contain {{environment:${env:ENVIRONMENT}}} rather than {{environment:my-fancy-env}}.
> The behavior is reproducible, however different applications behave differently, i. e. the same configuration yields different results (as in a race condition). The behavior is the same for the same config and application.
> Our current *workaround* is to downgrade to 2.17.1 for the time being.
> Is there maybe a connection to recently introduced raw values? Is this related to LOG4J2-3434?
