Use pattern matching instead of type casting.

[junghoon-vans]

If a type is resolved using the instanceof method, there is no need to explicitly cast the type.
This is thanks to the addition of JEP 394: Pattern Matching for instanceof in Java 16.

For example, a CriteriaFilterProcessor.java might change to the following:

AS-IS

if (value instanceof Box) {
    geoBBox = GeoBox.fromBox((Box) value);
}

TO-BE

if (value instanceof Box box) {
    geoBBox = GeoBox.fromBox(box);
}
