Hi Steven
I think this is the same conflict that I've seen after checking out
Xtext plugins as projects with sources.
Xtext, or more likely com.google.inject, cannot co-exist as both
resource and plug-in.
I'd like to know the answer too. It makes debugging harder than it
should be.
Regards

Hi Steven,
Xtext relies heavily on the internals of Antlr. That's why we require a
very specific version of the parser generator / parser runtime (3.2.0).
This bundle is shipped with Eclipse Xtext as a signed bundle. If you
have another antlr version installed and this one will be picked by
accident, chances are that the OSGi environment tries to load a class
from one bundle and another class from the other bundle, both classes
are in the same package but the second on is not signed. It is not
allowed to have signed classes and unsigned classes in the same package.
That's why you see the SecurityException.
You could try to be more explicit with the bundle dependencies. Don't
know whether that will help, though.
Regards,
Sebastian
