I did try adding some hints to help make it through these errors
hints.reflection().registerType(TypeReference.of("org.apache.logging.log4j.message.DefaultFlowMessageFactory"), MemberCategory.INVOKE_PUBLIC_CONSTRUCTORS)
hints.reflection().registerType(TypeReference.of("org.apache.logging.log4j.message.ParameterizedMessageFactory"), MemberCategory.INVOKE_PUBLIC_CONSTRUCTORS)
But I couldn't fix the error after these were added.
Here is a repo to help reproduce the error(without the hints): https://github.com/msosa/log4j2-native

Log4j2 isn't supported in a native image. It requires extensive changes to Log4j2 for it to work. Please see LOG4J2-2649 for further details.

@wilkinsona I have log4j2 on version [3.0.5,3.1.0[ and seems to work:
+--- org.springframework.boot:spring-boot-starter-log4j2 -> 3.0.9
| +--- org.apache.logging.log4j:log4j-slf4j2-impl:2.19.0
| | +--- org.slf4j:slf4j-api:2.0.0 -> 2.0.7

I just have that error when I bump to spring boot to 3.1+. That pull log4j2 2.20.0.

I use springboot3.3.2 with log4j 2.23 but failed.

@wilkinsona since it be resolved now, maybe we shall take some actions too...

Comment From: wilkinsona
Thanks for the nudge, @XenoAmess. It looks like the necessary changes are only available in 2.25 that has not yet been released. I'll re-open this so that we can investigate supporting Log4j2 once we've upgraded to 2.25 which is likely to be Spring Boot 3.5 at this point as we're nearing the end of the development cycle for 3.4.
In the meantime, you may be able to get things to work by adding some metadata to tell Graal to include org/springframework/boot/logging/log4j2/log4j2.xml in the native image.

yes I'm trying it this way and see if there be other troubles in it. would report you when I finish this learning.

@XenoAmess Any progress?

@XenoAmess Any progress?
not find any problem running with snapshot of log4j2 2.25.0-SNAPSHOT with spring-boot 3.3.4 it works smothly(smother than quite some other libs actually!) we just made a internal thirdparty-fork in our company and use it...not encounter any problem yet. well maybe a reason be we use metadataCopy with native-maven-plugin and get a 80%+ code coverage, which of course covers all usecases we have to log4j... but it works well without problem for my situation, so me be satisfied. thanks for your carefulness.

Does it mean Spring Boot supports log4j2 2.25.0-SNAPSHOT out-of-box now?

I don't know if it be officially declaired supported, but at least it works good on my situation...

The url protocol is jar:file when run in JVM, don't know what is it in native mode.
Is there anyway to work around?
