> so it appears I cannot iterate a source view and simultaneously copyFs() from
> it. This is a regression, and also seems rather counterintuitive - copyFs
> surely shouldn't modify the source view? Using the new
> .withSnapshotIterator() feature helps to work-around this, but for JCasUtil
> users this is not trivial to do at the moment (and then, it should be
> documented precisely what the CasCopier semantics in this regard is)..
