Hi Christian,
what you describe is perfectly legal. The plugin that Sven mentioned is
the org.antlr.generator which is not necessary to "run" your language.

Sebastian

It is even legal to ship the Antlr lib with the complete Eclipse IDE and create a commercial product that contains all of them.
The thing with Antlr is that Eclipse policies just do not allow to host the Antlr library at the Eclipse Orbit, since it failed IP approval. Antlr uses itself some library which does not comply with Eclipse IP policies, but also this is developed with a liberal license and allowed to be packaged, but just not at Eclipse. This is also one of the reasons why itemis provides its own distribution bundled with that.
Kind regards,
~Karsten
