With the fix for JDK-8042601, the sort output is not quite right, though it is several shades better,
the issue is that the Locale specific collator is not doing the right Collation so that we get a truly
case insensitive sort, TestOrdering.java has the following output:
add() - Method in class pkg1.UsedClass
add() - Method in class pkg1.ZZTop
add(double) - Method in class pkg1.UsedClass
add(Double) - Method in class pkg1.UsedClass
add(double) - Method in class pkg1.ZZTop
add(Double) - Method in class pkg1.ZZTop
add(double, byte) - Method in class pkg1.UsedClass
add(double, byte) - Method in class pkg1.ZZTop

instead it should look like this:
add() - Method in class pkg1.UsedClass
add() - Method in class pkg1.ZZTop
add(double) - Method in class pkg1.UsedClass
-add(Double) - Method in class pkg1.UsedClass
add(double) - Method in class pkg1.ZZTop
-add(Double) - Method in class pkg1.ZZTop
+add(Double) - Method in class pkg1.UsedClass
+add(Double) - Method in class pkg1.UsedClass
add(double, byte) - Method in class pkg1.UsedClass
add(double, byte) - Method in class pkg1.ZZTop
