Is there something subtle going on that makes jdk.internal.vm.StackChunk special?  We use the vmSymbols methods all over the place, and I thought there were rules about those classes only being loaded from the system classloader.  So why do we need to treat vmSymbols::jdk_internal_vm_StackChunk() different from, say, vmSymbols::java_lang_Class()?
