Bug Description:

While submitting a preformat code in Payments screen, the application

It starts with Jre 7U4 b10 and above including the latest build 17 provided

The request is not hitting the web-server and it hangs while trying 
to establish the connection through Java.

EVALUATION

confirmed the problematic behavior:

After I click "submit all", a new window titled "Processing..." with a progress bar saying "Processing request 1" pops up, and this is a modal window.  From now on, nothing proceeds further anymore.  And that progress window cannot be dismissed with any clicks.  Only way out is to kill the browser process.

I can reproduce on win7 32-bit, IE 9.

attached is applet client and browser jvm thread dump.

EVALUATION

confirmed bug is there since 7u4 b09, and is caused by this change:

7131316: 20ms latency always observed for LiveConnect round-trip in IE

backing out the above fix will make the problem go away.

but the fix is performance escalation from customer - need to better understand the performance fix and see if we can change it to work for this case too.

webrev of orig fix:  http://sa.sfbay.sun.com/projects/deployment_data/8/7131316.0/

for now, we will back out the above fix.   a new CR will be filed to re-fix the performance enhancement.
