> The change / fix in UIMA-4556 cause some problems when using a CSV file with whitespaces.
> When we have a dictionary with whitespaces between words and
> >> Param PARAM_DICT_REMOVE_WS is TRUE:
> When WS are visible in the token stream:
>  - words with spacers are not recognized (as expected).
> When WS are NOT visible in the token stream:
>  - all items in the dictionary will be recognized
>  - all items will also be recognized if you add whitespaces between words. For example:
IlikeRUTA, Ilike Ruta, I like Ruta all result in the same match.
> >> Param PARAM_DICT_REMOVE_WS is FALSE:
> When WS are visible in the token stream:
>  - not all entries in the dictionary will be recognized
> When WS are NOT visible in the token stream:
>  - also not all entries in the dictionary will be recognized
> The problem that this cause is that the default value to ignore whitespaces is always
true (hardcoded).
> {code:java}
> private IBooleanExpression ignoreWS = new SimpleBooleanExpression(true);
> {code}
> This is not correct because if you want to use whitespaces (if they are important) that
won't  work. The matcher should use the same value as set in the PARAM_DICT_REMOVE_WS parameter
or the value that is set via setIgnoreWS method.
> -I attached a patch to fix this issue.-
> I'm working on a patch.
