- * However, access checks are not implemented. See natField.cc for
- * _Jv_CheckFieldAccessibility as well as the missing getCaller.
- * Note that the idea is to have to compiler convert calls to
- * setXXX(...) and getXXX(...) to setXXX(CALLER, ...) and getXXX(CALLER, ...),
- * where CALLER is reference to the class that contains the calls to
- * setXXX or getXXX. This is easy for the compiler, and replaces
- * expensive stack and table searching with a constant.
