What version of JavaFX? Would you mind creating a bug for this?

Other responses in-line.

Two pieces of information are passed into the converter. The first is 
the value that was given in the style, e.g., "/mint/report_16x16.png". 
The second is the URL of the stylesheet as determined when the 
stylesheet is loaded. The stylesheet URL may be null, as would be the 
case for an in-line style.

If the resource is copied over to the build directory that eclipse uses 
on the class-path, then there shouldn't be a problem.
