>> I actually did add en empty line after the license header in HotSpotMethodDataAccessor.java at first, but then I noticed that all the other files in that directory except one (src/jdk.internal.vm.ci/share/classes/jdk.vm.ci.hotspot/src/jdk/vm/ci/hotspot/CompilerToVM.java) lack that empty line, so for consistency reasons I decided to not add it after all.
