I think the URL handler is a red herring. When the ClassLoader is wrong, EnableConfigurationPropertiesImportSelector$ConfigurationPropertiesBeanRegistrar.class isn’t on the class path of the ClassLoader that tries to load it so it’s correct that it fails to load.

When SpringClientFactory creates a context, it’s assuming that the thread context class loader will be the class loader that should be used by the child context. That holds true on Java 8 but does not hold true on Java 11. When running on Java 8, the TCCL is a TomcatEmbeddedWebappClassLoader. When running on Java 11, the TCCL is a ClassLoaders$AppClassLoader. The thread in both cases is a worker thread in a fork join pool. This looks like https://bugs.openjdk.java.net/browse/JDK-8172726 to me with the code relying on a bug that’s been fixed in Java 9.

I think the child context should be explicitly configured to use the ClassLoader from its parent:

if (this.parent != null) {
	// Uses Environment from parent as well as beans
	context.setParent(this.parent);
	context.setClassLoader(this.parent.getClassLoader());
}

This appears to fix the problem in my local testing.

I was able to replicate this issue in separate project. This project need service registry

./gradlew bootRun doesnt have this issue

but

./gradlew bootJar
and running java -jar build/libs/feign-0.0.1-SNAPSHOT.jar results in this problem when you invoke following url http://localhost:8080/hi

Environment

OpenJDK 11.0.2 Spring Boot: 2.1.2.RELEASE Greenwich.RELEASE

feign.zip

Unfortunately I’ve absolutely no idea what is that special at this µService (maybe except that we use dynamically created feign clients here). Anyway, I’ll spend a few hours this week to dig a bit deeper. I’ll keep you informed about my analysis.
