JFXTabPane Generating Exception

[Nanakwame68]

I am working on a project using JavaFX and Scene Builder. But when I add JFXTabPane to the Scene, I get the following Runtime Exception which I cannot figure out the cause.

java.lang.ClassCastException: class com.sun.javafx.geom.BoxBounds cannot be cast to class com.sun.javafx.geom.RectBounds (com.sun.javafx.geom.BoxBounds and com.sun.javafx.geom.RectBounds are in module javafx.graphics of loader 'app') at javafx.graphics/com.sun.javafx.sg.prism.NGNode.applyTransform(NGNode.java:2484) at javafx.graphics/com.sun.javafx.sg.prism.NGNode.accumulateGroupDirtyRegion(NGNode.java:1226) at javafx.graphics/com.sun.javafx.sg.prism.NGNode.accumulateDirtyRegions(NGNode.java:1041) at javafx.graphics/com.sun.javafx.sg.prism.NGNode.accumulateGroupDirtyRegion(NGNode.java:1208) at javafx.graphics/com.sun.javafx.sg.prism.NGNode.accumulateDirtyRegions(NGNode.java:1041) at javafx.graphics/com.sun.javafx.tk.quantum.ViewPainter.paintImpl(ViewPainter.java:248) at javafx.graphics/com.sun.javafx.tk.quantum.PresentingPainter.run(PresentingPainter.java:91) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.runAndReset(FutureTask.java:305) at javafx.graphics/com.sun.javafx.tk.RenderJob.run(RenderJob.java:58) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1130) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:630) at javafx.graphics/com.sun.javafx.tk.quantum.QuantumRenderer$PipelineRunnable.run(QuantumRenderer.java:125) at java.base/java.lang.Thread.run(Thread.java:832) Am using JavaFX15 Windows 10 64bit SceneBuilde 10
