Richard Eckart de Castilho commented on UIMA-3234:

I am considering to not cover this in uimaFIT and instead resolve it as part of 
UIMA-1524 (new iteration API in UIMA core).

> Currently there is one exception type in CasUtil.selectSingle(CAS cas, Type 
> type) method for the case if CAS does not contain an Annotation or CAS 
> contains more than one Annotation. However, I sometimes need to differentiate 
> between these two cases in exception handling. A new method like, 
> selectSingleOrNull(...) could solve this problem: return null if no 
> Annotation, RuntimeException if multiple Annotations.
> Currently to handle this problem I just use CasUtil.select(...) and check for 
> the size of the returned collection.
