Re: [equinox-dev] Java8 and JavaFX8
|
Hi Neil,
Thanks for the insight into this. It's exactly this kind of information
we need to assemble to find a way to solve the problems we'll all face
with once JavaFX8 is shipped.
My believe is that Oracle will not ship OSGi enabled JavaFX-jars and I
think the decision to ship as part of the JRE/JDK is already made.
If I get you right equinox isn't following the other OSGi spec when only
consulting the bootcloader for the system bundle? Tom what is the reason
for that? Could equinox by default consult the extension classloader?
