| 114 | NOTE about use of any ctor or function call that can trigger a safepoint/GC: | |||

| 137 | ||||

| 47 | // line number table, and indexed from the end of the method. We do not compress the |
| 48 | // checked exceptions table since the average length is less than 2, and it is used |
| 49 | // by reflection so access should be fast. We do not bother to compress the local |
