> Tests in ` HashCodeBuilderTest ` depends on `HashCodeBuilder.reflectionHashCode`. The logic of `reflectionHashCode` appends the fields returned by `java.lang.Class.getDeclaredFields`. The order of fields being appended will affect the calculated HashCode.
> However, `java.lang.Class.getDeclaredFields` does not guarantee any specific order and thus, test can fail if the order is different, (i.e., it generates a different hash code). "The elements in the returned array are not sorted and are not in any particular order" (reference: [https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#getDeclaredMethods--)|https://docs.oracle.com/javase/8/docs/api/java/lang/Class.html#getDeclaredMethods--]
