Build ID: I20070625-1500

Steps To Reproduce:
1. profile HeapTest monitoring execution time analysis
with show execution statistics selected
2. press enter once
3. pause the agent
4. refresh the method statistics and note the times for 
methodB
5. resume the agent, press enter in the console
6. reset the statisics view - notice methodB times
are now much smaller. methodB hasn't been called 
again while the agent is monitoring.


More information:
In once test on windows XP with the 4.4.0.2 release 
I got the times.

Base      Avg Base  Cumulative Calls
0.013089  0.013089  0.013556     1
0.000022  0.000022  0.000037     1

for below the pause and after process termination for methodB

HeapTest is a test program from the profiler automated test framework.
/org.eclipse.tptp.ac.testautomation/automation-files/external_classes/HeapTest.java

it executes its methods in the order:
methodA
methodB
<pause>
methodA
methodB
<resume>
methodA

This doesn't happen for execution flow configured.

Hey Alan, do you recall if this was WinXP on EM64T?

Pretty sure it was XP. Our EM64T test host is W2K3. Wouldn't be suprised if it reproduced everywhere though. I am sure I saw it on Vista or EM64T in the last pass.

Confirmed with 4.4.0.3, IBM Java 1.5 and Windows XP.

I'm unable to reproduce the bug with the second 4.5 candidate build driver (TPTP-4.5.0-200711050917) on the same machine and with the same version of Java, and also unable to reproduce on a Vista machine. The defect seems to have been fixed indirectly by another patch after 4.4.0.3 was released.

Please change the target to the 4.5 iteration when this Bugzilla was resolved.
