For Safari, Firefox and Opera, they are both not using v8 as javascript engine. In this sense, this patch serves as a chromium-specific bug-fixing.  It just provides a chance to solve such an issue but depending on the implementation in browser-side. 

In order to make chromium throwing the correct message set by NPN_SetException, chromium itself needs to apply another patch as described at http://codereview.chromium.org/8576001/

I had a try on Safari/Firefox/Opera, they also can't throw the expected message set by NPN_SetException. 

As far as I concerned,  this patch is the simplest solution for solving this issue for chromium/v8. I have also tried other solution, but will involve more changes even if NPAPI interface spec.
