It fits into splitUI pretty well, especially if you reduce the size of the test UI frame. Yet you'll have convert `JFrame` to `JPanel` or `Box`.

You can find a sample usage in #17847 or #17608 in [Collate2DPrintingTest.java](https://github.com/openjdk/jdk/blob/69fe7d9651cd759eea0495a0b7bf8c356d9b93a6/test/jdk/java/awt/print/PrinterJob/Collate2DPrintingTest.java#L96-L104).
