This is very much tied to the NPN_SetException bug. The fix is to save off the current ExecState in a static (or per-thread) static, and then throw the exception in that ExecState. I tried saving the ExecState on the Instance, however that doesn't work for Obj-C (since it's a static method), and doesn't work well for JS/C++ either since you have to be thrown an JavaScriptObject in order to be able to get back to an Instance. I may find time to finish up my patch, but right now real work is distracting... 86478 5 ddkilzer 2008-07-20 10:41:54 -0700 <rdar://problem/6089187> 86509 6 ddkilzer 2008-07-20 15:26:10 -0700 Related to Bug 19936? 405154 7 eric 2011-05-17 10:48:38 -0700 This is stll likely a bug, but Gears no longer cares since Gears is dead. 1876868 8 ap 2022-06-20 17:03:45 -0700 NPAPI is gone.
