> Some TokenFilters have numeric arguments in their constructors. They should throw {{IllegalArgumentException}}
for negative or meaningless values. 
> Here is some examples that demonstrates invalid/meaningless arguments :
> {code:xml}
>  <filter class="solr.LimitTokenCountFilterFactory" maxTokenCount="-10" />
> {code}
> {code:xml}
>  <filter class="solr.LengthFilterFactory" min="-5" max="-1" />
> {code}
> {code:xml}
>  <filter class="solr.LimitTokenPositionFilterFactory" maxTokenPosition="-3" />
> {code}
