Incorrect notNull assertion on parameter type in JobParameter

[parksjin01]

In JobParameter constructor there are duplicated assertion which check value parameter is not null.

spring-batch/spring-batch-core/src/main/java/org/springframework/batch/core/JobParameter.java

Line 50 in d3bb0de

public JobParameter(@NonNull T value, @NonNull Class<T> type, boolean identifying) {

public JobParameter(@NonNull T value, @NonNull Class<T> type, boolean identifying) {
	Assert.notNull(value, "value must not be null");
	Assert.notNull(value, "type must not be null");
	this.value = value;
	this.type = type;
	this.identifying = identifying;
}

With annotation of construction parameter and message in second Assert.notNull,
I guess second assertion might be intended to check that type parameter value is not null.

If my guess is correct, then how about change second assertion to check type parameter instead of value
