Jasper segnala che i componenti non vengono visualizzati correttamente nel nodo Swing JavaFX

Per la creazione di Jasper Report in JavaFX 11 sto usando report dinamici. Sto caricando il report all'interno di Swing Node ma il report Jasper viene visualizzato solo se faccio clic sull'area del riquadro dello stack e tutti gli altri componenti sono visibili solo se passo con il mouse su tutti quei componenti. I componenti e il contenuto del report non vengono caricati all'istante anziché visualizzati al passaggio del mouse e il report viene visualizzato quando si scorre il riquadro dello stack.

Poiché questo era il bug in Java 8 e sembra essere stato risolto, ma anche in Java 11 sto riscontrando lo stesso problema.

Dal momento che non ricevo alcuna risposta e come suggerito da Kleopatra ho creato un codice riproducibile minimo. Per favore, guarda questo.

Produzione

1. Dopo aver fatto clic sul pulsante Carica rapporto è visibile solo un'icona di salvataggio, nessun rapporto è visibile.

2. Dopo aver fatto clic su Stack Stack Area now, il report è visibile.

3. Dopo aver passato il mouse su un'altra icona ora l'icona Stampa è visibile.

4. Dopo aver passato il mouse sopra anche altre icone, vengono visualizzate una ad una.

Dopo aver verificato il wiki OpenJDK per i flag di debug OpenJFX , potresti provare a seguire.

È possibile forzare l'utilizzo del renderer software. Cambia inpom.xml

l'output è quindi
