Phillip Webb 1beee5700c Don't close early when SecurityManager present
Update `JarFile` and `JarFileWrapper` classes so that they no longer
close the `JarFile` early if a `SecurityManager` is in use.

Prior to this commit, the closed `JarFile` would cause (an ultimately
swallowed) NPE in `ZipFile` which manifested itself as a
`ClassNotFoundException` when starting the app.
