使用jpackage打包JavaFX应用后启动报错：无法启动JVM

打包使用的jpackage命令 #

.\jpackage.exe
--input C:\Users\My\Documents\NetBeansProjects\MyFX\target\
--dest C:\Users\My\Documents\NetBeansProjects\MyFX\
--name "MyFX"
--main-jar C:\Users\My\Documents\NetBeansProjects\MyFX\target\MyFX-2.0.jar
--main-class my.myfx.App
--module-path 'C:\Program Files\Java\jmods\\'
--add-modules javafx.controls,javafx.fxml,java.sql --win-console

启动报错信息 #

启动生成的程序时提示报错：Unable to Launch JVM，控制台输出中包含错误栈信息：Circular loading of URL stream handler providers detected

主类MyFX.App代码 #

package my.myfx;

public class App extends javafx.application.Application {

    public static void main(String[] args) {

疑问 #

• 是否需要添加更多库或JMod？
• 该循环加载报错与启动失败问题有何关联？
