<p>Hi Ben,</p>
<p>Can you elaborate on the issue you had with writing a minimal

<p>thanks,</p>

a test case in jtreg would be very helpful. <br>
test/jdk/com/sun/jdi/BreakpointTest.java would be a good
starting point <br>
for a new test. Note however this might be an IDE
interaction issue, and <br>
you might not be successful in writing a jtreg test case the
reproduces <br>
the problem. But that in itself would be useful to know.<br>
