Gluon mobile for a Spring application : ch.qos.logback.classic.Logger initialisation

Question

I have a JavaFX application that is based on Spring Framework. I'm trying to make it working as an Android application.

I'm using gradle and so the gluonfx-gradle-plugin. (v 1.0.18)

When running the nativeCompile task, I get the following error :

[mer. avr. 19 15:21:06 CEST 2023][INFO] [SUB] Caused by: com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: No instances of ch.qos.logback.classic.Logger are allowed in the image heap as this class should be initialized at image runtime. Object has been initialized by the io.netty.util.NetUtil class initializer with a trace:

[mer. avr. 19 15:21:06 CEST 2023][INFO] [SUB] . To fix the issue mark ch.qos.logback.classic.Logger for build-time initialization with --initialize-at-build-time=ch.qos.logback.classic.Logger or use the the information from the trace to find the culprit and --initialize-at-run-time= to prevent its instantiation.

I have tried to solve the problem adding this block in gluonfx block of the build.gradle :

gluonfx {
  ...
    compilerArgs = ["--trace-object-instantiation=ch.qos.logback.classic.Logger",
                    "--initialize-at-run-time=ch.qos.logback.classic.Logger"
    ]
  ...
}

But this doesn't produce any change on the nativeCompile result.

In addition to this problem. I have a lot of Warning :

[mer. avr. 19 15:33:19 CEST 2023][INFO] [SUB] Warning: Could not register io.netty.handler.codec.compression.Lz4FrameDecoder: queryAllPublicMethods for reflection.

Reason: java.lang.NoClassDefFoundError: org/jboss/marshalling/ByteInput. ...

Are there important ?

Please, can someone give me some guidance to solve this problem ?

Thank you.

Edit :

I have solved this problem following this [issue] (javafx graalvm Error: Classes that should be initialized at run time got initialized during image building). For me, what worked was to add in the build.gradle :

compilerArgs = ["--trace-object-instantiation=ch.qos.logback.classic.Logger",
            "--allow-incomplete-classpath",
            "--initialize-at-run-time=io.netty.util.internal.logging.Log4JLogger"]

And the file resources/META-INF/substrate/config/initbuildtime with the following content :

org.slf4j.LoggerFactory
ch.qos.logback.classic.Logger
org.slf4j.simple.SimpleLogger
org.slf4j.impl.StaticLoggerBinder
ch.qos.logback.core.spi.AppenderAttachableImpl
ch.qos.logback.core.status.StatusBase
ch.qos.logback.classic.Level
ch.qos.logback.core.status.InfoStatus
ch.qos.logback.classic.PatternLayout
ch.qos.logback.core.CoreConstants
org.slf4j.MDC
ch.qos.logback.core.util.StatusPrinter
ch.qos.logback.core.util.Loader

Doing this, I can create the executable (nativeLink).

But when running the application with nativeRun, the application stop immediately with the following error :

[mer. avr. 19 18:29:00 CEST 2023][INFO] [SUB] Caused by: java.lang.NoSuchMethodException: org.apache.logging.log4j.message.DefaultFlowMessageFactory.()

I'm using @Log4J2 with lombok. It seems something was not correctly compiled.
