ExtensionMethod failed to compile in Eclipse

[daniel-exceed]

using lombok 18 in exlipse oxygen 4.7.3.a, im trying to use this extensions class:
public class ReflectionUtils {
public static String getAnnotationValue(Class<?> clazz, Class<? extends Annotation> anno) {
if (!clazz.isAnnotationPresent(anno)) {
return null;
}

	try {
		return (String)anno.getDeclaredMethod("value").invoke(clazz.getAnnotation(anno));
	} catch (IllegalArgumentException | IllegalAccessException | SecurityException | InvocationTargetException | NoSuchMethodException e) {
		return null;
	}
}

}

in another class like this:
@ExtensionMethod({ReflectionUtils.class})

and call it like this:
public String getField(Class<?> clazz, String field) {
return FieldsMap.get(clazz.getAnnotationValue(Entity.class)).get(field);
}

my eclipse cant compile the entire class claiming:
Internal compiler error: java.lang.ArrayIndexOutOfBoundsException
maven compiles fine.
also, when i use an extension method with only 1 parameter (the object i extend) it compiles fine.

what can be done to make it work?

im attatching the error log of eclipse

lombok error.log

I have the same/simliar problem in Eclipse. It does compile successfully using javac however.

import java.util.Optional;
import lombok.experimental.ExtensionMethod;

class Extensions {
	public static <K, V> Optional<V> getOpt(Map<K, V> map, K key) {
		return Optional.ofNullable(map.get(key));
	}
}
@ExtensionMethod({Extensions.class})
public class Main2 {
	public static void main(String[] args) {
		Map<String, Integer> map = Map.of("key", 1);
		System.out.println(map.getOpt("missing"));
	}
}

Errors occurred during the build.
Errors running builder 'Java Builder' on project 'MyProject'.
java.lang.ArrayIndexOutOfBoundsException

The same for me, using Lombok 1.18.6. and Eclipse
Version: 2018-09 (4.9.0)
Build id: 20180917-1800

I could simplify the code to

public class Extensions {
	public static Optional<String> getOpt(String s, int index) {
		return Optional.ofNullable(null);
	}
}

@ExtensionMethod({Extensions.class})
public class Main2 {
	public static void main(String[] args) {
		final String s = "a";
		System.out.println(s.getOpt(7));
	}
}

The problem disappears when I remove the index argument.
