This looks off. Is this auto-generated order? 

The Style Guide (https://github.com/openjdk/jdk/blob/master/doc/hotspot-style.md) says:


- Put conditional inclusions (#if ...) at the end of the section of HotSpot include lines. 
  This also applies to macro-expanded includes of platform dependent files.
- Put system includes in a section after the HotSpot include lines with a blank line
  separating the two sections.
``` 

So maybe there is a bug in the include sorter?
