Zoran Regvart created CAMEL-16804:
-------------------------------------
Summary: NullPointerException when using try-with-resources and
MainConfigurationProperties
Key: CAMEL-16804
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
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}
