Description ngx472 2016-02-15 18:48:35 UTC 
Did not find duplicate for this one although stak trace begins the same
Here it's rooted at 
org.openide.loaders.FolderList.carefullySort(FolderList.java:600)

Do not ask for repro, it's transient when editing folder property and asking to "sort by Modification Time"

Hint(?): the folder is big and under SVN

java.lang.IllegalArgumentException: Comparison method violates its general contract!
