Bundle location:http://j2se.east/arc/1.6.0_23/nightly/2010-10-29.15_39

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. clear deployment cache
2. open the following url with java console open:
http://sqeweb.sfbay.sun.com/jsn/users/fred/master_run/deployment/src/plugin/CustomProgressBar/CustomProgressBar/html/liveconnect/PosiveNegative.html
or
http://sqeweb.sfbay.sun.com/jsn/users/fred/master_run/deployment/src/plugin/CustomProgressBar/CustomProgressBar/html/liveconnect/BasicLiveConnectTestNegative.html

In the progress bar's constructor method, it tried to call a javascript method "testJS", which actually does not exist.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A JSException should be printed in java console
ACTUAL -
No exception is printed

REPRODUCIBILITY :
This bug can be reproduced always.
