I have a simple Schedule like below which should run every 30 minutes from 6pm to 10:30pm.
import javax.ejb.Schedule;
import javax.ejb.Schedules;
import javax.ejb.Singleton;
#Singleton
public class XxxJob {
#Schedules({
#Schedule(minute = "0,30", hour = "18-22", dayOfWeek = "Mon-Fri",
timezone = "Europe/London", persistent = false)
})
public void process() {
//...
}
}
But when I check the details of the timer on the Wildfly console, I see this:
{"time-remaining" => 30039141L,"next-timeout" => 1498757400000L,"calendar-timer" => true,"persistent" => false,"schedule" => {"year" => "*","month" => "*","day-of-month" => "*","day-of-week" => "Mon-Fri","hour" => "18-22","minute" => "0,30","second" => "0","timezone" => "Europe/London","start" => undefined,"end" => undefined}}
It says the next run (next-timeout) is at 1498757400000L (epoch millis) but that corresponds to 2017-06-29T18:30+01:00[Europe/London] and not 18:00.
Why is the timer scheduled to run at 18:30 and not at 18:00?
Note 1: if I amend the schedule to only run at 18:00 it works as expected:
#Schedule(minute = "0", hour = "18", dayOfWeek = "Mon-Fri",
timezone = "Europe/London", persistent = false)
Note 2: if I remove the #Schedules annotation it works as expected too.

I tried Java scheduler and quartz scheduler. Using java scheduler the code runs every 15 min. But still it does not work. I need to run the process every day from 6 pm to 12 am. every 15 min. And if the mail is found. stop the scheduler for the day and restart the process the next day at 6 pm. Syste.exit(0) stops the code but I need to restart it the next day.
You said:
I need to run the process every day from 6 pm to 12 am. every 15 min. And if the mail is found. stop the scheduler for the day and restart the process the next day at 6 pm.
You could simplify your problem by scheduling a task to run every 15 minutes around the clock. Let that task check (a) whether the daily chore was performed, and (b) the time-of-day and date.
The idea here is to let you task run needlessly, but ever so briefly, around the clock. Checking the current moment, and comparing to when the chore was last performed, take a minuscule amount of CPU time and memory. So there really is no point to bothering with suspending the checks for part of each day.
public class EveningEmailCheckingTask implements Runnable
{
final private ZoneId zoneId;
final private LocalTime startTime ;
private ZonedDateTime whenEmailRetrieved;
public EveningEmailCheckingTask( final ZoneId z , final LocalTime lt )
{
this.zoneId = Objects.requireNonNull( z ) ;
this.startTime = Objects.requireNonNull( lt ) ;
this.whenEmailRetrieved = ZonedDateTime.now( this.zoneId ).minusDays( 1 ) ; // Initialize a value so our main code can skip null check.
}
#Override
public void run()
{
ZonedDateTime now = ZonedDateTime.now( this.zoneId ) ;
// See if chore has been completed successfully today.
LocalDate then = this.whenEmailRetrieved.toLocalDate() ;
LocalDate today = now.toLocalDate() ;
if( then.isBefore( today ) )
{
if( now.toLocalTime().isBefore( this.startTime ) ) { return ; }
// … Perform chore.
// … If email received, update `this.whenEmailRetrieved`.
}
else if( then.isEqual( today ) )
{
return ; // Daily chore already performed.
}
else if( then.isAfter( today ) )
{
// Houston, we have a problem. The task was performed in the future.
}
else
{
// Should never reach this point. Defensive check in case our if-tests above are flawed.
}
}
}
Instantiate.
EveningEmailCheckingTask task = new EveningEmailCheckingTask( ZoneId.of( "Asia/Kolkata" , LocalTime.of( 18 , 0 ) ) ;
Create a ScheduledExecutorService, and remember it. You’ll need to shutdown that service before your app exits, otherwise the backing thread pool can continue indefinitely like a zombie 🧟♂️.

We have a problem with JavaFX MediaPlayer for more than a month now. We read and tried all the similar problems here, nothing worked.
Simplest example: It's an info app with 2 videos from a folder played continualy in a loop. After some time (sometimes 2h, sometimes 2 days)
videos start to slow down, duration is longer, occasional freeze, sound becomes distorted.
OS: win7 64b (Ultimate) SP1
Intel Celeron CPU N3150 #1.6GHz
8 GB Ram
java 1.8 and 1.10, 64b
Tried:
OS update, latest.
Drivers updates, other drivers.
JDK 64b, 1.8 latest updates, JDK 1.10 latest.
Changing code (adding dispose, closing, setting null, caching... every suggestion on stackoverflow)
Changing video encoders: MPEG-4, H.264 and H.264-HD, 1500/2000/4000/8000 kbps, 25fps
Changing resolutions: 1280x720,
Sound: AAC, 1 and 2 channels, 48 & 44 kHz, 128kbps bit rate and others. Tried videos without audio.
Almost every possible combination of these video/sound encoders, bitrates, resolutions, framerates ...
We profiled for memory leaks: memory grows for some time and it stops growing. It's ok (we think).
Nothing we tried has worked. No errors, no exceptions on MediaView, Media, Player. No system events.
Confusing: we noticed that that in normal operations CPU is 20-30%, but, when videos start to freeze, it's lower, 5-15%.

What is the Python analog of Time4J's code example:
// duration in seconds normalized to hours, minutes and seconds
Duration<?> dur = Duration.of(337540, ClockUnit.SECONDS).with(Duration.STD_CLOCK_PERIOD);
// custom duration format => hh:mm:ss
String s1 = Duration.Formatter.ofPattern("hh:mm:ss").format(dur);
System.out.println(s1); // output: 93:45:40
// localized duration format for french
String s2 = PrettyTime.of(Locale.FRANCE).print(dur, TextWidth.WIDE);
System.out.println(s2); // output: 93 heures, 45 minutes et 40 secondes
It is easy to get 93:45:40:
#!/usr/bin/env python3
from datetime import timedelta
dur = timedelta(seconds=337540)
print(dur) # -> 3 days, 21:45:40
fields = {}
fields['hours'], seconds = divmod(dur // timedelta(seconds=1), 3600)
fields['minutes'], fields['seconds'] = divmod(seconds, 60)
print("%(hours)02d:%(minutes)02d:%(seconds)02d" % fields) # -> 93:45:40
but how do I emulate PrettyTime.of(Locale.FRANCE).print(dur, TextWidth.WIDE) Java code in Python (without hardcoding the units)?
babel module allows to get close to desired output:
from babel.dates import format_timedelta # $ pip install babel
print(", ".join(format_timedelta(timedelta(**{unit: fields[unit]}),
granularity=unit.rstrip('s'),
threshold=fields[unit] + 1,
locale='fr')
for unit in "hours minutes seconds".split()))
# -> 93 heures, 45 minutes, 40 secondes
It handles locale and plural forms automatically e.g., for dur = timedelta(seconds=1) it produces:
0 heure, 0 minute, 1 seconde
Perhaps a better solution would be to translate the format string manually using standard tools such as gettext.
If you're using Kotlin, I just came across a similar problem with the Kotlin Duration type with localized formatting and because I couldn't find a good solution, I wrote one myself. It is based on APIs provided starting in Android 9 (for localized units), but with a fallback to English units for lower Android versions so it can be used with lower targeting apps.
Here's how it looks like on the usage side (see Kotlin Duration type to understand 1st line):
val duration = 5.days.plus(3.hours).plus(2.minutes).plus(214.milliseconds)
DurationFormat().format(duration) // "5day 3hour 2min"
DurationFormat(Locale.GERMANY).format(duration) // "5T 3Std. 2Min."
DurationFormat(Locale.forLanguageTag("ar").format(duration) // "٥يوم ٣ساعة ٢د"
DurationFormat().format(duration, smallestUnit = DurationFormat.Unit.HOUR) // "5day 3hour"
DurationFormat().format(15.minutes) // "15min"
DurationFormat().format(0.hours) // "0sec"
As you can see, you can specify a custom locale to the DurationFormat type. By default it uses Locale.getDefault(). Languages that have different symbols for number than romanic are also supported (via NumberFormat). Also, you can specify a custom smallestUnit, by default it is set to SECOND, so milliseconds will not be shown. Note that any unit with a value of 0 will be ignored and if the entire number is 0, the smallest unit will be used with the value 0.
This is the full DurationFormat type, feel free to copy (also available as a GitHub gist incl. unit tests):

I'm trying to process CQEngine's ResultSet using Scala's foreach, but the result is very slow.
Following is the snippet of what I'm trying to do
import collection.JavaConversions._
val query = existIn(myOtherCollection, REFERENCE, REFERENCE)
val resultSet = myIndexCollection.retrieve(query)
resultSet.foreach(r =>{
//do something here
})
Somehow the .foreach method is very slow. I tried to debug by putting SimonMonitor and change the .foreach using while(resultSet.hasNext), surprisingly, every call to hasNext method takes about 1-2 seconds. That's very slow.
I tried to create the same version using Java, and the Java version is super fast.
Please help
