[jira] [Commented] (LOG4J2-2604) Generate reflect-config.json for
GraalVM during annotation processing
[ https://issues.apache.org/jira/browse/LOG4J2-2604?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16876704#comment-16876704 ]
YangGuanchao commented on LOG4J2-2604:
--------------------------------------
[~mattsicker] Which version do we plan to release this feature?
And also instead of providing a (separate?) tool for generating a {{reflect-config.json}} configuration file, we can also provide one separate jar such as named log4j2-graal-feature , when we want running on GraalVM to compile Native Image ,wo can only add this jar to the calsspath.

> Key: LOG4J2-2604
> URL: https://issues.apache.org/jira/browse/LOG4J2-2604
> Project: Log4j 2
> Issue Type: New Feature
> Components: Configurators
> Reporter: Remko Popma
> Priority: Major
>
> See [https://github.com/oracle/graal/issues/1209] and [https://github.com/oracle/graal/issues/808]
> Currently log4j2 cannot be used in GraalVM native images because it uses reflection.
> Graal SubstrateVM can [deal with reflection|https://github.com/oracle/graal/blob/master/substratevm/REFLECTION.md] when it’s clear to the AOT compiler what classes, methods and fields are reflected on. The log4j plugin mechanism is too dynamic for the automatic reflection analysis.
> This can be solved by providing a {{reflect-config.json}} configuration file, which may be embedded in the jar under {{META-INF/native-image/some/path/}}.
> The annotation processor is the natural place to generate this configuration file, so that applications that provide custom Log4j components will have the necessary {{META-INF/org/apache/logging/log4j/core/config/plugins/reflect-config.json}} to accompany their {{META-INF/org/apache/logging/log4j/core/config/plugins/Log4j2Plugins.dat}} file in their jar.
> It may be convenient to provide a (separate?) tool for generating a {{reflect-config.json}} configuration file from the {{META-INF/org/apache/logging/log4j/core/config/plugins/Log4j2Plugins.dat}} file in any jar.
