When doing some testing with TestFX running in headless mode
via Monocle I came across a BufferOverflowException.
One thing to check: make sure your JavaFX Scene is not exceeding the
screen size of the Monocle Headless platform, which is 1280 × 800 px.
Otherwise, you'll get a BufferOverflowException like the following,
where I exceeded the height by one pixel:

The maximum screen sizes for some Monocle platforms are:
Linux: The framebuffer size
Headless: 1280 × 800 px
VNC: 1024 × 600 px
You can use the "fbset" command to find or change the Linux framebuffer
size:
$ sudo fbset
mode "1024x768-76"
# D: 78.653 MHz, H: 59.949 kHz, V: 75.694 Hz
geometry 1024 768 1024 768 32
timings 12714 128 32 16 4 128 4
rgba 8/16,8/8,8/0,8/24
