Description
If an applet while doing any Java > JS communication raises an  netscape.javascript.JSException then further Java > JS communication is not possible. 
This behavior is not reprodcucible with earlier releases i.e. everything is working fine till 6u17.

Steps to reproduce:
1)Install 6u18 PIT build-03
2) Load the following applet inside the Browser http://sqeweb.sfbay.sun.com/deployment2/jitu/plug-bug/popupblocker/PopUpBlockerJSNegative.html
3) Click on the  button "open new window". This should raise an netscape.javascript.JSException
4) Now try to click on the button "Do Something else" or try clicking again on  "open new window". If actions fails to respond then bug is reproduced
Comments
EVALUATION Problem: the fix for 6809648 didn't take JS exception into account. If a JS exception occurs during the first call, it thinks that there's still a JS call on stack and forbids the subsequent calls. Fix: perform decrementActiveJSCounter() in a finally block.

EVALUATION This regression is caused by the fix for 6809648 (JSObject.eval() gets blocked by modal JDialog).
