| 28 | # to detect the correct ordering of the output since it |
| 29 | # is produced by multiple threads and can be interleaved |
| 30 | # in many different ways. |

| 156 | This test should be run and checked manually. |
| 157 | |
| 158 | If this works right, you should see StepEvents/Breakpoint events for lines |
| 159 | 8, 9, 6, 7, 8, 9, 6, .... for thread jj11 |
| 160 | and |
| 161 | 20, 21, 18, 19, 20, 21, 18, ... for thread jj2 |
| 162 | |
| 163 | Since both threads are running at the same time, these |
| 164 | events can be intermixed. |
| 165 | |
| 166 | The bug is that you will frequently see step events missing. |
| 167 | EG, you will see |
| 168 | 8, 9, 8 |
| 169 | or |
| 170 | 20, 21, 20, 21 |
| 171 | etc |
| 172 | |

| 175 | This is bug: |
| 176 | 4619349 Step Over fails in a multi threaded debuggee |
