      The JVMCI method HotSpotResolvedJavaFieldImpl.hashCode() currently does not consider the holder of a field when computing the hash code. Due to that, lots of collisions are happening when HotSpotResolvedJavaFieldImpl objects are being used in a hash map as keys. This impacts performance.

      Doing the change is not urgent but it should be backported to JDK 9 in some update release.
