It traces back to here: https://github.com/scenerygraphics/scenery/blob/549fb2afc7b758ea6caadf15c71b3b403e001025/src/main/kotlin/graphics/scenery/volumes/TransferFunctionEditor.kt#L277

When I poke through the debugger it looks like using the relative paths is a problem. I would be happy to be corrected. However, when I set a breakpoint at the above line, then in the debugger I can use resources within the volumes package (e.g. colormap-hot.png) but if I even try something like ../volumes/colormap-hot.png then it fails.
