154 **************************************************************** |
|
155 This test should be run and checked manually. |
|
156 |
|
157 If this works right, you should see StepEvents/Breakpoint events for lines |
|
158 8, 9, 6, 7, 8, 9, 6, .... for thread jj11 |
|
159 and |
|
160 20, 21, 18, 19, 20, 21, 18, ... for thread jj2 |
|
161 |
|
162 Since both threads are running at the same time, these |
|
163 events can be intermixed. |
|
164 |
|
165 The bug is that you will frequently see step events missing. |
|
166 EG, you will see |
|
167 8, 9, 8 |
|
168 or |
|
169 20, 21, 20, 21 |
|
170 etc |
|

|
172 ============================================================ |
|
173 At some point you might get the msg 'Nothing suspended' |
|
174 This is bug: |
|
175 4619349 Step Over fails in a multi threaded debuggee |
|
176 |
|
177 Kill the test and rerun it if this happens. |
