Create new phase Validate

[osmman]

It would be nice to have phase which provides Bean validation (javax.validation) on Job instances.
Use case:

@Validate // add validation phase for class
public class ValidatedJob extends DummyJob {

    @NotNull // define validation criteria
    private String param;

    @Size(min = 1) // define validation criteria
    private List<String> list = Collections.EMPTY_LIST;
}
