Description Sherry Zhou 2007-09-06 23:51:28 UTC 
beta1 build 0709050000 or 0709060000

1. Open attached project and reverse engineer.
2. Create sequence diagram for operation test>basic>testConditionIf 

Tested on 4 different systems and here are the results.
1. IDE crashed on windows xp which is 1GHz CPU, 1GB RAM. It complains stack overflow. The log 
file hs_err_pid764.log can be found in attachment.
2. IDE hangs on solaris sparc which is 1GHz CPU, 2GB RAM. The threaddump can be found in attachment
3. IDE is very slow on another windows system and ubuntu. Both systems have 2GHz CPU and 2GB RAM

Comment 4 Peter Lam 2007-09-07 18:45:58 UTC 
Just go straight to reverse engineer operation to sequence diagram the 3rd operation "testConditionIf3" from class
testConfitionIf. After the sequence diagram is generated and displayed, the memory usage jumped up to 515+MB and then
came down immediately to ~3MB and the the memory usage for all other processes in the whole system causing the whole
system to be not responsive at all.
Comment 5 Peter Lam 2007-09-07 18:53:36 UTC 
ops, comment not yet completed.
... the memory usage for all other processes in the whole system went crazy (memory usage all went down to just around
2-3MB) as well and causing the whole system to be not responsive at all. The source for the 3rd operation
"testConditionIf3" seems to be complicated with lots of combined fragments filing up in the generated sequence diagram.
Maybe the source is too complicated to handle.
Comment 6 Kris Richards 2007-09-07 18:55:35 UTC 
[update] this does not occur on Mac. No memory issue at all. Checking XP and Solaris.
Comment 7 Viktor Lapitski 2007-09-08 02:47:43 UTC 
fixed.
Comment 8 Viktor Lapitski 2007-09-10 07:26:21 UTC 
comitted the fix into realease60_beta1 branch also.
Comment 9 Peter Lam 2007-09-11 06:36:43 UTC 
verified in beta 1 build 200709101200. 
Sherry, Please verify in your platforms as well. thanks.
Comment 10 Sherry Zhou 2007-09-11 17:45:30 UTC 
verified on beta1 build 200709101200. Tested on a Solaris and XP system which IDE has hang . 
The problem is gone.
