We have issues like JDK-8349637 and JDK-8305324 which probably could have avoided if we used more flexible/standard way to provide fuzzy data to our tests. For example, we could provide 'mandatory' sequence or data (that test developer wants to execute), and the new DataProvider would add standard 'tricky' values (zero, +-1, max and min values, infinities/NaNs for floats, etc.) along with some random ones.
