Problem description:
It has been noticed that sometimes applets fails to write onto plugin trace on windows platforms when run with mozilla and trace level is set to 5. It's happening with most of the liveconnect applets. In the trace following lines which are getting written onto the console even the appplet is done with it's execution:
liveconnect: JavaScript: calling Java system code
liveconnect: JavaScript: default security policy = http://sqeweb.sfbay.sun.com
liveconnect: JavaScript: calling Java system code
liveconnect: JavaScript: default security policy = http://sqeweb.sfbay.sun.com

Fore details pls refer to following logs :
http://sqeweb.sfbay.sun.com/deployment4/jitu/tigerb51_deployment/ATF/win32MZ_trace_level_5/logs/report_OJI_Method_Public_log.txt
(no output from test applets , applet supposed to write STATUS: <testcase_name> PASSED/FAILED)

same applet when run with trace level set equal to 0
http://sqeweb.sfbay.sun.com/deployment4/jitu/tigerb51_deployment/ATF/win32MZ/logs/report_OJI_Method_Public_log.txt
You can notice the STATUS: <testcase_name> PASSED inside the plugintrace

I've already discussed this issue with Xiaobin/Deva.
The test cases works fine on linux/solaris with mozilla irrespective of trace level value
