>                 URL: https://issues.apache.org/jira/browse/CAMEL-16804
>             Project: Camel
>          Issue Type: Bug
>          Components: camel-main
>    Affects Versions: 3.11.0
>            Reporter: Zoran Regvart
>            Assignee: Zoran Regvart
>            Priority: Minor
>             Fix For: 3.11.1, 3.12.0

>
> When using try-with-resources with {{MainConfigurationProperties}}, {{MainConfigurationProperties::close}} might be invoked twice leading to {{NullPointerException}} on shutdown:
> {code}
> ...
> Caused by: java.lang.NullPointerException
> 	at all//org.apache.camel.main.MainConfigurationProperties.close(MainConfigurationProperties.java:88)
> 	at all//io.github.zregvart.dbzcamel.dbtodb.App.main(App.java:26)
> 	... 4 more
> {code}
> I.e. the Camel's shutdown will invoke {{MainConfigurationProperties::close}}, but also the try-with-resources bit if used like:
> {code}
> try (MainConfigurationProperties configure = main.configure()) {
>     configure.addRoutesBuilder(Route.class);
>     main.run(args);
> } catch (final Exception e) {
>     throw new RuntimeException(e);
> }
> {code}
