A SmPL ellipsis was specified for a search approach so that additional source code would be tolerated between an assignment to a local variable and the corresponding null pointer check. But such code should be restricted. * The local variable must not be reassigned there. * It must also not be forwarded to an other assignment target. Take additional casts for these code exclusion specifications into account together with optional parentheses.
