@Schedule cause IllegalArgumentException: daysOfMonth: []

[hantsy]

This issue is existed in the former 8.0.0-M9 and I tried to verify today and found it is still existed in the new GlassFish 8.0.0-M10.

The server log.

The @Schedule annotation is used like this.

@ApplicationScoped
public class StandUpMeeting {

    @Asynchronous(
            executor = "java:comp/MyScheduleExecutor", // can not refer by Qualifier???
            runAt = {
                    @Schedule(
                            daysOfWeek = {
                                    DayOfWeek.MONDAY,
                                    DayOfWeek.TUESDAY,
                                    DayOfWeek.WEDNESDAY,
                                    DayOfWeek.THURSDAY,
                                    DayOfWeek.FRIDAY
                            },
                            hours = 8
                    ), // daily standup
                    @Schedule(daysOfMonth = {1}, hours = {12}), // monthly meeting,
                    @Schedule(cron = "*/5 * * * * *") // every 5 seconds for test purpose
            }
    )
    void inviteToMeeting() {
        LOGGER.log(Level.ALL, "running scheduled tasks....");
        // ...
    }
}

And call this bean in REST resources.

@RequestScoped
@Path("invites")
public class InviteResources {

    @Inject Invite invite;
    @Inject StandUpMeeting meeting;

    @POST
    public Response sendInvites() {
        meeting.inviteToMeeting();
        return Response.ok().build();
    }
   
    // ...
}

Will need to upgrade concurro once this

• Schedule exception when parsing daysOfMonth glassfish-concurro#114

is released.

With

• Compatibility certification request for Eclipse GlassFish 8.0 M10 for Web Profile jakartaee/platform#1052

claiming GF8.0.0-M10 with Concurrency TCK is fine, I guess TCK is missing test for this case.

May be good to suggest a new test to be added for this in the concurrency tck.
