Hi Max,
Now I remembered one detail I left and came back again.
The file:
features\org.jboss.tools.xulrunner.feature\feature.properties
Has a interesting license block mentioning GPL & LGPL.
Maybe its something that can be removed as that feature is actually MPL/EPL (3 plugins MPL, 1 plugin EPL).
[maybe a Jira for this one]
Would it make sense to create a page at http://www.jboss.org/tools for the license descriptions?
That page could include a table with all the features available under JBoss Tools, and what licenses apply.
I think that would help a lot other people.
(I could volunteer for that last one)
Cheers,
Igor
