With the help of Pavel Safrata I found the problem. I have this css file 
which sets the style and the images of the toggle buttons:


#pill-left {
-fx-padding: 5;
-fx-border-image-source: url(/com/dx57dc/images/left-btn.png);
-fx-border-image-slice: 4 4 4 4 fill;
-fx-border-image-width: 4 4 4 4;
-fx-border-image-insets: 0;
-fx-border-image-repeat: stretch;
-fx-background-color: null !important;
}
#pill-left:selected { -fx-border-image-source: 
url(/com/dx57dc/images/left-btn-selected.png); }

#pill-left .label {
-fx-text-fill: #d3d3d3;
-fx-effect: dropshadow( one-pass-box , rgba(0,0,0,0.75) , 0, 0.0 , 
0 , -1 );

}

#pill-left:selected .label {
/* -fx-text-fill: black; */
-fx-text-fill: white;
-fx-effect: dropshadow( one-pass-box , white , 0, 0.0 , 0 , 1 );
}
#pill-center {
-fx-padding: 5;
-fx-border-image-source: url(/com/dx57dc/images/center-btn.png);
-fx-border-image-slice: 4 4 4 4 fill;
-fx-border-image-width: 4 4 4 4;
-fx-border-image-insets: 0;
-fx-border-image-repeat: stretch;
-fx-background-color: null !important;
}
#pill-center:selected { -fx-border-image-source: 
url(/com/dx57dc/images/center-btn-selected.png); }

#pill-center .label {
-fx-text-fill: #d3d3d3;
-fx-effect: dropshadow( one-pass-box , rgba(0,0,0,0.75) , 0, 0.0 , 
0 , -1 );

}
#pill-center:selected .label {
-fx-text-fill: black;
-fx-effect: dropshadow( one-pass-box , white , 0, 0.0 , 0 , 1 );
}
#pill-right {
-fx-padding: 5;
-fx-border-image-source: url(/com/dx57dc/images/right-btn.png);
-fx-border-image-slice: 4 4 4 4 fill;
-fx-border-image-width: 4 4 4 4;
-fx-border-image-insets: 0;
-fx-border-image-repeat: stretch;
-fx-background-color: null !important;
}
#pill-right:selected { -fx-border-image-source: 
url(/com/dx57dc/images/right-btn-selected.png); }

#pill-right .label {
-fx-text-fill: #d3d3d3;
-fx-effect: dropshadow( one-pass-box , rgba(0,0,0,0.75) , 0, 0.0 , 
0 , -1 );

}
#pill-right:selected .label {
-fx-text-fill: black;
-fx-effect: dropshadow( one-pass-box , white , 0, 0.0 , 0 , 1 );
}

The images are placed at the Java package: com.dx57dc.images
What is the proper way to load images from css in Java 8?

 Well, the only solution that I can think of is to place the images and the
 css file into one folder.
