Release Note:
In order to avoid class leaks due to creating multiple user code class loaders and loading class multiple times in a recovery case, I would suggest to bind the lifetime of a user code class loader to the lifetime of a slot. More precisely, the user code class loader should live at most as long as the slot which is using it.
