[native-image] server usage doesn't produce reliable images across builds

I have my simplest spring app. If I compile with --no-server I always get the same image and same output. If I try to run with a server, my image changes size across multiple builds and the output from my app changes. Here are two images built in sequence with the server:
Compile with server, first build (69 seconds):

/\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \
( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \
\\/ ___)| |_)| | | | | || (_| | ) ) ) )
' |____| .__|_| |_|_| |_\__, | / / / /

Notice all the logging is gone in the second image. To recreate:
git clone https://github.com/spring-projects-experimental/spring-graal-native
cd spring-graal-native/spring-graal-native-feature
git checkout upgrade_19_3
mvn clean package
cd ../spring-graal-native-samples/commandlinerunner
Modify compile.sh to remove --no-server then run it.

Forgot to say, this is mac (pre catalina) with dev build of graal (commit #5a9edeb3ef) on Java 11 base.

FYI I am not able to build spring-graalvm-native in a reliable way without --no-server using GraalVM 20.1.0 so we are going to use this option by default for now.
