Spring There may be unexpected result in ClassUtils#resolvePrimitiveClassName(String name)

Affects: 4.x and 5.x

I'm not sure whether there is a bug or not.

ClassUtils#resolvePrimitiveClassName(String name)

public static Class<?> resolvePrimitiveClassName(@Nullable String name) {
    Class<?> result = null;
    // Most class names will be quite long, considering that they
    // SHOULD sit in a package, so a length check is worthwhile.
    if (name != null && name.length() <= 8) {
            // Could be a primitive - likely.
        result = primitiveTypeNameMap.get(name);
    }
    return result;
}

The length of "boolean[]" is 9. How to resolve the primitive class like boolean[].class?
