I guess what I don't understand about the current fix is, where is the
context class loader getting changed from the boostrap class loader in the
first place? The current approach is to capture the class loader of
MesosExecutorDriver and set it to the context class loader and then set it
back. Isn't this also just the `sun.misc.Launcher` class loader?
