154****************************************************************
155This test should be run and checked manually.
156
157If this works right, you should see StepEvents/Breakpoint events for lines
158   8, 9, 6, 7, 8, 9, 6, ....   for thread jj11
159and
160  20, 21, 18, 19, 20, 21, 18, ... for thread jj2
161
162Since both threads are running at the same time, these
163events can be intermixed.
164
165The bug is that you will frequently see step events missing.
166EG, you will see
167  8, 9, 8
168or
169  20, 21, 20, 21
170etc
171
172============================================================
173At some point you might get the msg 'Nothing suspended'
174This is bug:
175   4619349 Step Over fails in a multi threaded debuggee
176
177Kill the test and rerun it if this happens.
