FULL PRODUCT VERSION :
JDK 1.4 latest plugin with IE 5.*, 6.0

FULL OPERATING SYSTEM VERSION :NT 2000


ADDITIONAL OPERATING SYSTEMS :ALL



A DESCRIPTION OF THE PROBLEM :
Hi,
Our product uses Liveconnect to interface with Javascript.
The job of the Java side is to distribute the data to the
Javascript clients. We are passing in a vector object to
the JS, in which JScript tries to enumerat thru the
vector. This all works fine without plugin, but when using
1.4 plugin, we run into a crash when enumerating.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1.Enclosed Java code: compile it and drop it in the
webserver
2.Enclosed HTML code


EXPECTED VERSUS ACTUAL BEHAVIOR :
  To be able to iterate thru the vector using enumerator.
  From analysis we have done it seems like any object that is
not primitive type; there is a problem.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
After the crash:


An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : unknown exception code occurred at PC=0x77E87E08
