| * The bug (JDK-4525714) is about failing PopAsynchronousTest test. |
| * This is another test of the same issue. The bug occurs when trying |
| * to walk the stack of a deoptimized thread. We can do this |
| * by running in -Xcomp mode and by doing a step which causes deopt, |
| * and then a 'where'. This will cause not all the frames to be shown. |
