In jclouds we usually provide builders that return the result of a "self()"
methos instead of returning "this". This allows proper builder inheritance.
See an api metadata builder examples [1] (and have a look at its superclass
too).
If the builder you are using does not follow that pattern
Specifically, compare BaseApiMetadata.Builder.id with
UpdateImageOptions.Builder.name [1, 2]. Looks like Ignasi's hunch is
correct ;-)
To be fair to say, I think UpdateImageOptions.Builder simply predates
the self() pattern, so it's probably just ready for an update.
