Using 'instanceof' with patterns
Reports instanceof
with patterns and suggests converting them to ordinary instanceof
with casts.
This inspection makes it possible to move instanceof
with patterns to a codebase using an earlier Java version by applying the quick-fix.
Note that the result can be not completely equivalent to the original instanceof
with patterns when a complex expression before instanceof
is used. In this case this expression will be reevaluated.
