// All dependencies on layout of actual Java classes should be kept here. |
|
37 |
// If the layout of any of the classes above changes the offsets must be adjusted. |
|
38 |
// |
|
39 |
// For most classes we hardwire the offsets for performance reasons. In certain |
|
40 |
// cases (e.g. java.security.AccessControlContext) we compute the offsets at |
|
41 |
// startup since the layout here differs between JDK1.2 and JDK1.3. |
|
42 |
// |
|
43 |
// Note that fields (static and non-static) are arranged with oops before non-oops |
|
44 |
// on a per class basis. The offsets below have to reflect this ordering. |
|
45 |
// |
|
46 |
// When editing the layouts please update the check_offset verification code |
|
47 |
// correspondingly. The names in the enums must be identical to the actual field |
|
48 |
// names in order for the verification code to work. |
