Thank you for reporting this issue and taking the time to forward it to the ANTLR4IDE project. Unfortunately, I am sorry to say that I believe that this bug will not be fixed in the near future as this project is lacking contributors. I will leave it open for now...

By the way: When I try to open the link provided under the point internal reference I either get "404 – Page Not Found" or "You do not have access to this view: /incidents/597f0923e4b05728f8e899f8". I suppose the second one is due to saving privacy of Eclipse users.

The link is internal, you can't access it. Take it just as a reference. Mainly it contains the information from above.

You can leave the bug open, but I opened this one to close the issue reported to Eclipse as a 3rd party issue.
