/** Base class for jdk.internal.misc.Unsafe-based FieldAccessors for static |
2 | 36 |
fields. The observation is that there are only nine types of |
37 |
fields from the standpoint of reflection code: the eight primitive |
|
38 |
types and Object. Using class Unsafe instead of generated |
|
39 |
bytecodes saves memory and loading time for the |
|
40 |
dynamically-generated FieldAccessors. */ |
