Why the getSorted function sorts list of pairs with "(o1, o2) -> o2.first().compareTo(String.valueOf(o1.second()))".
And this cause "java.lang.IllegalArgumentException: Comparison method violates its general contract!"

Issue caused by new java sort algorithm in jdk1.8. will need to be fixed later. Workaround is to pass "-Djava.util.Arrays.useLegacyMergeSort=true" to java/jvm

@jerrygaoLondon Thank you for your reply. My another question is why the lambda funtion compare o2.first to o1.second. The first element is a string, but the second element is a integer. Is this a logical error?
