Radial gradient used as a Stroke

[goddard at seznam.cz]

Hello,

I've got this piece of code https://github.com/g0dd4rd/TKE/blob/master/src/tke/Encounter.java where I use Circle as a clip for Rectangle to see the background. The Circle has a Stroke, but this Stroke is not shown when used with a clip.
Does it work as designed?
My goal is to use RadialGradient as a Stroke. I haven't found an issue for it for JIRA, so I'm asking here.

Regards, Jiri
