Re: [equinox-dev] Java8 and JavaFX8

Hi Tom,

I'll try to catch you on IRC on Friday. I really like to stay away from
framework hooks and all the stuff (p2 magic).

I know for sure that I can fix all equinox problems the way I fix them
today :-)

Just out of curiosity can one provide ones own Execution Environment?
The next problem we face after we have solved the runtime problem is
tooling. PDE currently only takes the Execution Environment into
consideration when calculation the access rules for packages from the
system.bundle - although I'd favor fixing PDE :-)

It is just a thought experiment. What happens if the packages are part
of the profile but on the extension-classpath, would equinox fail?

Let's discuss on IRC. Neil do you want to join in which would mean we'd
have to set a more formal date.

Tom
