----------------------------------------------
Resolution: Fixed
> Use iteratorWithSnapshot in the select methods
> ----------------------------------------------
>
> Key: UIMA-4427
> URL: https://issues.apache.org/jira/browse/UIMA-4427
> Project: UIMA
> Issue Type: Improvement
> Components: uimaFIT
> Reporter: Richard Eckart de Castilho
> Assignee: Richard Eckart de Castilho
> Fix For: 2.2.0uimaFIT
>
>
> Since UIMA 2.7.0, there are "iterateWithSnapshot" methods that safeguard
> against modifying the indices while iterating over them. uimaFIT could avoid
> concurrency problems in client code by consistently using these new methods
> at the expense of some performances. I would expect though, that whoever
> wants to the the last piece of performance out of the code would not use the
> uimaFIT select methods anyway - they would try to optimize iteration order at
> all cost.
