Substance UI和自定义JComponent的TitledBorder问题

Question

我正在使用BorderFactory创建一个带有Substance UI主题Swing用户界面的有标题的边框，我遇到了如下所示的异常。我试过使用LineBorder，它工作得很好，但似乎Substance UI以某种方式干扰了TitledBorder。边框绘制在paintComponent中通过以下方式完成：

if (getBorder() != null) {
   getBorder().paintBorder(this, g, 0, 0, getWidth(), getHeight());
}

这本身可能是不正确的。我的问题本质上是如何在不创建父JPanel并设置它的情况下让TitledBorder工作，这看起来有点像是逃避。

这是laf-widget内部的一个bug。它目前假设每个图形对象都有一个GraphicsConfiguration和一个与之关联的GraphicsDevice。我有一个叫做insubstantial的物质分支，它是has a fix的。

当前快照的maven坐标是固定的，是com.github.insubstantial:substance:6.3-SNAPSHOT，而快照存储库位于https://oss.sonatype.org/content/repositories/snapshots/。我预计在6月底左右发布6.3系列。
