| **************************************************************** |
| This test should be run and checked manually. |
| |
| If this works right, you should see StepEvents/Breakpoint events for lines |
| 8, 9, 6, 7, 8, 9, 6, .... for thread jj11 |
| and |
| 20, 21, 18, 19, 20, 21, 18, ... for thread jj2 |
| |
| Since both threads are running at the same time, these |
| events can be intermixed. |
| |
| The bug is that you will frequently see step events missing. |
| EG, you will see |
| 8, 9, 8 |
| or |
| 20, 21, 20, 21 |
| etc |
| |
| ============================================================ |
| At some point you might get the msg 'Nothing suspended' |
| This is bug: |
| 4619349 Step Over fails in a multi threaded debuggee |
| |
| Kill the test and rerun it if this happens. |
