Very confusing exception when using storing an int constant to a long field

[FroMage]

This code exhibits the exception:

public class GizmoTest {
    
    public static class MyEntity {
        boolean isPersistent;
        long version;
    }
    
    public static void main(String[] args) {
        try(ClassCreator modelClass = ClassCreator.builder().className("test")
                .classOutput((foo, bar) -> {
                    System.err.println("Printing "+foo+": "+bar);
                })
                .build()){

            FieldDescriptor fieldDescriptor = FieldDescriptor.of(MyEntity.class, "version", long.class);
            try(MethodCreator creator = modelClass.getMethodCreator("foo", void.class, MyEntity.class)){
                ResultHandle entityParam = creator.getMethodParam(0);
                creator.writeInstanceField(fieldDescriptor, entityParam, creator.load(0));
                creator.returnValue(creator.loadNull());
            }
        
        }
    }
}

When running it, I get:

Exception in thread "main" java.lang.NegativeArraySizeException
	at org.objectweb.asm.Frame.merge(Frame.java:1222)
	at org.objectweb.asm.MethodWriter.computeAllFrames(MethodWriter.java:1607)

	at io.quarkus.panache.rx.deployment.GizmoTest.main(GizmoTest.java:36)

Which is very hard to explain the cause is the load(0) which should be a load(0l)
