[webkit-help] memory leak in JSObjectMake?

I am using WebKit JSAPI to create my own JS object, looks like there is memory leak when calling JSObjectMake()/JSValueUnprotect().
My calling sequence like follow:
myJSClass = JSClassCreate(&my_jsclass_def);
myJSObj = JSObjectMake(context, myJSClass, NULL);
I looked into WebKit, after JSValueUnprotect was called, while garbage collector try to delete the object, ref-count of jsClass was not 0 at the time, so it was not deleted. If I have a big list of property or functions in myJSObj and frequently create/release the object, it will cause big memory problem.
I traced the reference counter of the object, there are two places to increase it:
1. creating JSCallbackObjectData
2. creating OpaqueJSClassContextData
While garbage collector deletes the object, the first one got deref but second one did not.
After I force to deref it, I saw ~OpaqueJSClass() was called. however still have problem to remove OpaqueJSClassStaticValuesTable
Can any one help to check if I missed some thing from my calling function or if it is memory leak in the API, any comment how to fit it?
