why can't these be required? what is special in common?

private?
can these can be static? so you walk the classes objects based on inheritance?

each one on own line to allow future add without modifying entire line.

why do you need the common?

why not take object and map?
public static void validateParameters(Object o, ParametersMap map) {
# get @Parameters annotation
# check aginst map
}
this can be generic and not related to anything in application.
please see it as (Parameters, ParametersMap, @Parameters, ParametersValidator)
can be used in other projects as well.

why is this needed? why can't we only walk the parameters map?
