36 // 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.

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.
