JavaScriptCore seems to have been almost entirely relicensed under APSL; there are at most just two or three files still under GPL (involving date parsing), and in many configurations those are no longer compiled.
JavaScriptCore code is either LGPL or BSD licensed, depending on whether it derives from the original KJS source base or is new code written by Apple. There's no APSL code in JavaScriptCore last I checked.
Where do you see that, as far as I can tell JSC is still LGPL.
