> Tests in MultilineRecursiveToStringStyleTest.java, RecursiveToStringStyleTest.java, ToStringBuilderTest.java depends on ReflectionToStringBuilder.appendFieldsIn. It appends the fields returned by java.lang.Class.getDeclaredFields. 
> 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--)
