Log4j2 is broken with SubstrateVM

[sdeleuze]

Log4j2 is broken with SubstrateVM, I have created a repro project.

In regular JVM

ERROR StatusLogger No Log4j 2 configuration file found. Using default configuration (logging only errors to the console), or user programmatically provided configurations. Set system property 'log4j2.debug' to show Log4j 2 internal initialization logging. See https://logging.apache.org/log4j/2.x/manual/configuration.html for instructions on how to configure Log4j 2

It does not compile with native image:

error: unsupported features in 27 methods

Tested with GraalVM 1.0.0 RC10 latest snapshot (built from master)

With the latest master and the following config files:

Click to expand resource-config.json

you should be able to build the native image:

$ native-image -H:ReflectionConfigurationFiles=$PWD/config/reflect-config.json -H:ResourceConfigurationFiles=$PWD/config/resource-config.json --allow-incomplete-classpath -H:+ReportExceptionStackTraces --delay-class-initialization-to-runtime=org.apache.logging.log4j.core.pattern.JAnsiTextRenderer -cp target/log4j2-1.0-SNAPSHOT-jar-with-dependencies.jar com.sample.App

and get the expected output:

$ ./com.sample.app
