You do know that he was agreeing to have copied 9 lines from one file, Timsort? And you do know that those 9 lines are just a range check? I mean: private static void rangeCheck(int arrayLen, int fromIndex, int toIndex) { if (fromIndex > toIndex) throw new IllegalArgumentException("fromIndex(" + fromIndex + ") > toIndex(" + toIndex+")"); if (fromIndex < 0) throw new ArrayIndexOutOfBoundsException(fromIndex); if (toIndex > arrayLen) throw new ArrayIndexOutOfBoundsException(toIndex); } Literally a rangeCheck. And not only that, 9 lines written by the stealer himself ( http://cr.openjdk.java.net/~martin/webrevs/openjdk7/timsort/raw_files/new/src/share/classes/java/util/TimSort.java http://cr.openjdk.java.net/~martin/webrevs/openjdk7/timsort/... ) and given to Sun/Oracle! Still, i agree with, Sun/Oracle do have the copyrights for that. Google needs to pay up, is ten bucks alright for this?
