java - How to terminate a scheduled thread when JavaFX Runtime exits? -

i'm looking on similar examples problem. have javafx app runs gui updates via thread running from: scheduledexecutorservice::scheduleatfixedrate.

this similar couple of other questions. 2 recognised situation these:

• javafx task threads not terminating
• how stop "javafx application thread"

the question need resolve, however, next step. target embedded application , there's no opportunity manually kill jvm-task, or other easy answers, etc. i'm afraid reboot reserved critically-serious.

we need ensure threads closed off in orderly way. i'm looking kind of call or event lets me register clean-up routine close-down stuff?

i thinking there ought 'something' in base class, javafx javafx.application.application deed.

• http://docs.oracle.com/javafx/2/api/javafx/application/application.html

is stop method might use or can register called when there stop fxmlcontroller?

at present when run javafx app netbeans, jvm process persists. stops further build scripts , locks jar file. netbeans gives option kill task. true solution means application/jvm closes-down orderly , neatly.

(update) ... looked javafx.application class use launch javafx app. implemented stop() method. here make sure i've called platform.exit() ...

///// //  @see //    -- http://docs.oracle.com/javafx/2/api/javafx/application/application.html#stop%28%29 // public void stop() {     platform.exit(); } 

this doesn't cure problem when running netbeans. need click stop [x] button 2 times, process stop when use kill button. if interested in progress reported bug: [bug 245284], there's small clock example demonstrate problem. when close window, netbeans process running panel still 'running'. can't build because jar file locked. @ least know manually kill development program.

• suggestions welcome . . .

i have partial solution cover fellow developers caught in situation. declare stop() method in in javafx app (called "mainapp" netbeans maven javafx template). there questions of course, first method.

• see: javafx application

stop called @ end of program. had call call platform.exit() close-down javafx runtime. i've added call shutdown other active executor threads, kept in list now, test solution.

 public class mainapp extends application  {       @override      public void start(stage stage) throws exception      {          .....      }           /**           *  close down application           *  @see           *   -- http://docs.oracle.com/javafx/2/api/javafx/application/application.html#stop%28%29           **/       @override       public void stop()       {           platform.exit();           for( scheduledexecutorservice sched : activeexecutorservices )           {               sched.shutdown();           }       }  }//mainappl class 

so commenting-out call shutdown , running javafx program, application finishes won't exit, , netbeans show running task. need manually click on kill-button in netbeans.

uncomment shutdown() call. when javafx application exits, dissappears netbeans running jobs. appears resolotion.

the remaining questions:

1. what correct order between platform.exit() , shutdown()?
2. with more 1 scheduledexecutorservice matter order used shut them-off? lifo or fifo?
3. is there better way?
4. ought netbeans able detect 'process overrun' , report problem. @ least leave , option ignore or fix program.

hopefyully assist next faces similar problem :-)
