我的JavaFX测试仅在Windows中失败，但在OSX和Linux中运行良好
这是stacktrace：

从堆栈跟踪中，触发异常(SLIVCodeAreaTest.java:14)的代码部分位于代码部分的private static final SLIVCodeArea声明中：
import static org.junit.Assert.assertTrue;
import org.junit.Test;
public class SLIVCodeAreaTest {
private static final SLIVCodeArea sEditor = new SLIVCodeArea(new SLICodeArea()) {
@Override protected void updateVisibleParagraphRange() {} };
private static final VEditorProblemList sProblemList =
new VEditorProblemList(sEditor, new SimpleObjectProperty<>(), false);
static { sEditor.aggregatedTextChanges().setAggregationEnabled(false); }

如果我从上面的初始化部分删除关键字 静态 ，则错误的堆栈跟踪将变为：

PS：测试在OSX中有和没有 静态 关键字。
相同的代码在Linux和MacOS中运行良好，但在Windows中失败。 有谁知道为什么？
答案 0 :(得分：0)
JavaFX，JUnit和任何java.lang.ExceptionInInitializerError的组合是异常Toolkit not initialized被抑制发生的指示。
要初始化JavaFX，您可以在运行单元测试之前等待new JFXPanel()完成。

根据Matlab FEATool Nonlinear Time dependent Heat Transfer Solution
公共类ExceptionInInitializerError扩展了LinkageError信号 静态初始化程序中发生意外异常。一个 抛出ExceptionInInitializerError以指示异常 在评估静态初始化程序或初始化程序期间发生 对于静态变量。
因为您没有发布Class ExceptionInInitializerError
我认为因为 newscreens 不是静态或是由 null 初始化，并且您尝试将null变量转移到数组。
