MultiException when custom jersey param throws exception

[Srikanth Chikkulapelly]

Here is my custom java 8 LocalDateTime param for @QueryParam annotation to convert. It converts YYYY-MM-DD format date to LocalDateTime (YYYY-MM-DD 00:00:00).

 

public class LocalDateTimeParam extends AbstractParam<LocalDateTime> {

     public LocalDateTimeParam(String input) {
        super(input);
    }


    @Override
    protected LocalDateTime parse(String input) throws Exception {
        return LocalDateTime.of(LocalDate.parse(input), LocalTime.MIDNIGHT);
    }

    @Override
    protected Response error(String input, Exception e) {
        // returns valid Response object here.
    }
}

The following MyBean is injected into resource method using @BeanParam annotation. Resource class is in RequestScoped lifecycle.

public class MyBean {

    @NotNull(message = "startDate must be specified")    
  @QueryParam("startDate")    
  private LocalDateTimeParam startDate;

}

When I send GET request with startDate query param it works great if the date format is valid (YYYY-MM-DD). However when I pass invalid date format, I expected it to return Response from LocalDateTimeParam. I received MultiException from HK2. I fixed this by having a custom exception mapper that returns WebApplicationException response. But this doesn't look right. Has anyone faced this before?

Here is parts of stacktrace.
