Monocle Framebuffer java.nio.BufferOverflowException

[nartz]

Hi,

I'm experiencing this error:

Exception in thread "JavaFX Application Thread" java.nio.BufferOverflowException at java.nio.IntBuffer.put(IntBuffer.java:769) at com.sun.glass.ui.monocle.Framebuffer.composePixels(Framebuffer.java:187) at com.sun.glass.ui.monocle.HeadlessScreen.uploadPixels(HeadlessScreen.java:118) at com.sun.glass.ui.monocle.MonocleView._uploadPixels(MonocleView.java:95) at com.sun.glass.ui.View.uploadPixels(View.java:771) at com.sun.prism.PresentableState.uploadPixels(PresentableState.java:295) at com.sun.javafx.tk.quantum.SceneState.access$001(SceneState.java:40) at com.sun.javafx.tk.quantum.SceneState.lambda$uploadPixels$307(SceneState.java:123) at com.sun.glass.ui.monocle.RunnableProcessor.runLoop(RunnableProcessor.java:92) at com.sun.glass.ui.monocle.RunnableProcessor.run(RunnableProcessor.java:51) at java.lang.Thread.run(Thread.java:745) java.nio.BufferOverflowException at java.nio.DirectIntBufferU.put(DirectIntBufferU.java:363) at com.sun.javafx.tk.quantum.UploadingPainter.run(UploadingPainter.java:153) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at com.sun.javafx.tk.RenderJob.run(RenderJob.java:58) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at com.sun.javafx.tk.quantum.QuantumRenderer$PipelineRunnable.run(QuantumRenderer.java:125) at java.lang.Thread.run(Thread.java:745)

I can't be sure if its exactly the same, but its possibly related to this patch

I'm using Java 8. Whats is the best way for me to try to incorporate this patch? Any help or recommendations are appreciated!

Thanks!

Seeing the exact same problem. Did you find a way to incorporate the mentioned patch?

The default headless screen size is 1280x800. If you set larger dimensions, then the BufferOverflowException can appear. That is what happened to me. So I did set the same dimensions for stage as the ones that are set for the headless screen size.

This repository is simply a copy of the official Monocle code found in the JFX repository: https://github.com/openjdk/jfx. We only maintain this repository for purposes of building the library to support headless testing with TestFX. Our apologies.
