There are a bunch of calls to `Collections.sort()` without a comparator specified  (at least in java.desktop):

https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/sun/java2d/Spans.java#L144
https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/sun/awt/DebugSettings.java#L278
https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/sun/swing/text/TextComponentPrintable.java#L787
https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/javax/swing/DefaultRowSorter.java#L1070
https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/javax/swing/DefaultRowSorter.java#L1204
https://github.com/openjdk/jdk/blob/master/src/java.desktop/share/classes/javax/swing/GroupLayout.java#L2137

It is also a wrapper to `list.sort(null)`. 

Is there any reason to not touch them along with this fix?
