This should offer slight performance benefit if a reflection object has its generic information accessed frequently, as reading a stable field is faster than reading a volatile field for cached objects. If the `genericInfo` fields are updated by JVMTI then they need to be declared `volatile` instead. In addition, some of the `genericInfo` fields may have been not thread-safe for their multiple field reads. ------------- PR: https://git.openjdk.java.net/jdk/pull/8742
