[jira] [Comment Edited] (LOG4J2-2649) Is Log4j2 considered to support successful static compilation under GraalVM?

    [ https://issues.apache.org/jira/browse/LOG4J2-2649?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16897475#comment-16897475 ]

Take a look at PropertiesUtil and ProviderUtil. You will find that they both use ServiceLoader. What you probably don't like is that ServiceLoader isn't being used to load the LoggerContextFactory. That is because Log4j wants to make sure the implementation it found matches the API version being asked for. ServiceLoader can't do that by itself so the service being loaded has that information along with the LoggerFactory class to be used.

> Oracle released GraalVM [https://github.com/oracle/graal] to support the static compilation of Java applications to Native Image, which can increase the startup speed of Java by at least 10 times. In the cloud native field, this basic technology is believed to be in the near future. Will be supported by more and more vendors, such as the Spring/Spring Boot community has supported or plans to support the feature of GraalVM, see this issue: [https://github.com/spring-projects/spring-framework/search?q=Graalvm&type=Issues] can support static compilation, so it is recommended that Log4j2 also need to support static compilation as soon as possible, and can be compiled correctly under GraalVM.
