This application is actually a tiny isolated part of the "func" application that I referred to in #497. The app there actually compiles now, but this one doesn't, so that's a bit weird?

The lines of code that start the stack trace for sure are using reflection in a way that is very hard to configure ahead of time, but this code path will never be hit in this application, so I thought the --report-unsupported-elements-at-runtime flag would be enough to get something runnable.

public class Autowires {

	private Bar bar;

	@Autowired
	public void setBar(Bar bar) {
		this.bar = bar;
	}

	public static void main(String[] args) {
		new Autowires().run();
	}

	private void run() {
		DefaultListableBeanFactory context = new DefaultListableBeanFactory();

		AutowiredAnnotationBeanPostProcessor post = new AutowiredAnnotationBeanPostProcessor();
		post.setBeanFactory(context);
		context.addBeanPostProcessor(post);
		context.registerBeanDefinition("bar",
				BeanDefinitionBuilder
						.genericBeanDefinition(Bar.class, () -> new Bar("bar"))
						.getRawBeanDefinition());
		context.autowireBean(this);
		System.err.println(context.getBean(Bar.class));
		System.err.println(bar);
	}

}

class Bar {

	private String value;

	public Bar() {
	}

	public Bar(String value) {
		this.value = value;
	}

	public String getValue() {
		return this.value;
	}

	public void setValue(String value) {
		this.value = value;
	}

	@Override
	public String toString() {
		return "Foo [value=" + this.value + "]";
	}

}

It runs fine with regular Java:

$ java -cp target/classes/:target/graal-test-0.0.1-SNAPSHOT-shaded.jar Autowires
Foo [value=bar]
Foo [value=bar]

Then

$ mx native-image -H:Name=auto -H:ReflectionConfigurationFiles=${HOME}/dev/scratch/graal/reflect.json --report-unsupported-elements-at-runtime -cp /home/dsyer/dev/scratch/graal/target/classes/:/home/dsyer/dev/scratch/graal/target/graal-test-0.0.1-SNAPSHOT-shaded.jar Autowires

@dsyer thanks for reporting. This is indeed weird. We'll look into it.

[peter-hofer]

This appears to be the same problem as #784, which was fixed in our master branch (but the fix did not make it into 1.0-RC10).
