Include .openjfx native libraries in jpackage image

[e-Gyi-qO]

Can it be that a .openjfx directory was recently created at my user directory because of sparrowwallet?
I used the suggestions at faq.html#im-running-on-a-high-resolution-screen-and-sparrow-icons-and-text-are-tiny, and faq.html#sparrow-is-too-big-for-my-screen. Which boils to suggesting _JAVA_OPTIONS=-Dglass.gtk.uiScale=.... Does such usage, or maybe any usage of sparrowwallet, would lead to the creation of a .openjfx directory? If the answer is yes, can the faq.html point that out?

Yes, this is standard behaviour in JavaFX. The location of the .openjfx folder (into which is extracted the native libraries JavaFX requires) can be changed, for example

JAVA_OPTIONS=-Djavafx.cachedir=/another/folder /opt/sparrow/bin/Sparrow

It might be possible to include these libraries in the application installation instead, avoiding this. I'll rename and keep this issue open to investigate.
