Test case:
EXECUTE:
1. Create CDI Project
2. Create New CDI Qualifier:

import static java.lang.annotation.ElementType.FIELD;
import static java.lang.annotation.ElementType.METHOD;
import static java.lang.annotation.ElementType.PARAMETER;
import static java.lang.annotation.ElementType.TYPE;
import static java.lang.annotation.RetentionPolicy.RUNTIME;

import java.lang.annotation.Documented;
import java.lang.annotation.Retention;
import java.lang.annotation.Target;

import javax.inject.Qualifier;

@Target( { TYPE, METHOD, PARAMETER, FIELD })
@Retention(RUNTIME)
@Documented
@Qualifier
@interface Chunky
{
   
   boolean realChunky() default true;
   boolean unrealChunky();
   
   int number() default 5;
   int size();
   
   long long_number() default 1000;
   long long_size();
   
   short short_number() default 2;
   short short_size();
   
   float probability() default (float)13.5;
   float probability2();
   
   double double_probability() default 27.3;
   double double_probability2();
   
   char charachter() default 'E';
   char charachter2();
   
   byte bbb() default (byte)3;
   byte bebebe();
}

3. Create interface:

interface Animal
{

}

4. Create CDI Bean:

@Chunky(bebebe = 10, charachter2 = 10, double_probability2 = 10, long_size = 10, probability2 = 10, short_size = 10, size = 10, unrealChunky = false)
class Sheep implements Animal
{

}

4. Create class:

import javax.inject.Inject;


public class Farm_Broken1 {
	  @SuppressWarnings("unused")
	  @Inject private Animal animal;
}

5. Build project
