/**
* {@link Callable} that nominates another claassloader for serialization.
*
*
* For various reasons, one {@link Callable} object (and all the objects reachable from it) is
* serialized by one classloader.
* By default, the classloader that loaded {@link Callable} object itself is used,
* but when {@link Callable} object refers to other objects that are loaded by other classloaders,
* this will fail to deserialize on the remote end.
*
*
* In such a case, implement this interface, instead of plain {@link Callable} and
* return a classloader that can see all the classes.
*
* In case of Hudson, {@code PluginManager.uberClassLoader} is a good candidate.
