java - StyleManager not applying CSS properly -

i'm encountering issue stylemanager in java 1.8.0_25. if apply css file scene directly css appear properly. however, if try , use stylemanager apply css file across scenes, css not applied.

here's simple program demonstrate issue

public class test extends application {      public static void main(string[] args) {         launch(args);     }      @override     public void start(stage primarystage) throws exception {         application.setuseragentstylesheet(null);         parent node = new fxmlloader(getclass().getresource("testing.fxml")).load();         scene scene = new scene(node); //      stylemanager.getinstance().adduseragentstylesheet("tabpanetest.css");         scene.getstylesheets().add("tabpanetest.css");         primarystage.setscene(scene);         primarystage.show();     }  } 

testing.fxml:

<?xml version="1.0" encoding="utf-8"?>  <?import java.net.*?> <?import java.lang.*?> <?import javafx.scene.control.*?> <?import javafx.scene.layout.*?>   <vbox xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1">    <children>       <tabpane maxheight="-infinity" maxwidth="-infinity" minheight="-infinity" minwidth="-infinity" prefheight="400.0" prefwidth="600.0" tabclosingpolicy="unavailable">         <tabs>           <tab text="untitled tab 1">             <content>               <anchorpane minheight="0.0" minwidth="0.0" prefheight="180.0" prefwidth="200.0" />             </content>           </tab>           <tab text="untitled tab 2">             <content>               <anchorpane minheight="0.0" minwidth="0.0" prefheight="180.0" prefwidth="200.0" />             </content>           </tab>         </tabs>       </tabpane>    </children> </vbox> 

tabpanetest.css:

.tab-pane .tab {     -fx-padding: 3 6 1 6;     -fx-border-style: none;     -fx-border-color: transparent;     -fx-border-width: 0;     -fx-border-insets: 2;     -fx-background-radius: 3 3 0 0;     -fx-background-insets: 0 2 0 2;     -fx-background-color: linear-gradient(green 80%, blue 100%); } 

without using stylemanager, it's suppose like:

however, when comment out applying css directly scene , using stylemanager instead get:

has experienced issue stylemanager? unfortunately, have big application, uses stylemanager apply css scenes

call stylemanager.getinstance().adduseragentstylesheet("tabpanetest.css"); after primarystage.show();.

i encountered same issue since java 8u40 , fixed way. unfortunately have not found public api adding global stylesheet, too.
