------------------------------------------------------------------------------ 
src/hotspot/share/jvmci/jvmciJavaClasses.hpp
  28 #include "runtime/jniHandles.inline.hpp"

.hpp files are not permitted to #include .inline.hpp files.

We've fixed most violations (I think there are still a few lingering
ones that have not yet been disentangled); please don't add new ones.
