java/util/AbstractList/CheckForComodification.java has been @ignore-d due to JDK-4992226, which is closed as WNF, and normally I'd just reopen 4992226, but the test is a regression test for JDK-4902078, which itself is closed as WNF; hence I think the test just needs to be removed.

should it be decided that the test should stay, please repurpose this bug to update @ignore so the 1st word in it is bugid, 4992226, this would make our tools happier.
