Running JavaFX-11 applications from within Eclipse fails

[Johan Vos]

Hi Tom,

Nice workaround, but what do you think needs to be done to fix it? Can the
java.library.path somehow be changed in a plugin or so?
Renaming the native libraries in JavaFX would probably solve this, but that
seems the wrong solution to me.
