> There are several occurrences where exception is used to control flow.
> Code such as
> {noformat}
> try  {
>  // block A
> } catch (ClassCastException e) {
>  // block B
> }
> {noformat}
> where "block A" is trying to cast an object "o" to "SomeClass", should be changed to
> {noformat}
> if (o instanceof SomeClass)  {
>  // block A
> } else {
>  // block B
> }
> {noformat}
