Hello,
We use:
- Vaadin 8.5.2
- Tomcat 8.5.16
We have a sporadic error loading images in the application.
After the error has occurred, only restarting the application will help. Reloading the page does not correct the error. All other data are displayed correctly, the problem only affects the images.
Does anyone have any clues?
To display the image, we use the Image Component:
new Image(null, new StreamResource(() -> new ByteArrayInputStream(getImageData()), UUID.randomUUID().toString() + ".png"));
