我使用最新的Install4J制作了一个安装程序，并希望在raspberry pi上安装该软件包进行测试。
它正在运行最新的Raspbian图像及最新更新和openJDK v.1.8.0.40
如果我尝试以无人值守模式启动安装程序（-q），我会得到一个＆＃34;启动安装程序...＆＃34;消息，然后我得到一个NullPointerException。
这是控制台输出：
pi@raspberrypi:~ $ ./plentyBase.sh -q

相同的安装程序在虚拟机中的Ubuntu 16.04 LTS上正常工作。
编辑： 我认为它来自JPanel init来获取FontMetrics？
在此处找到：NPE when calling new JPanel() in headless (RepaintManager.currentManager)
所以它看起来像是install4J中的一个错误。
如果我在raspberry pi上以desktop / gui模式打开安装程序，安装程序工作正常。
任何想法有什么不对？
