Thank you for the bug report @eliaweiss .

Unfortunately, as I explained in the readme, I haven't used Eclipse for a few years, so I'm unlikely to fix this. Additionally, I haven't done any Eclipse development for about 4 years, and as a result don't have an Eclipse dev environment set up - so I'm not in a good position to review and merge PRs.

However, if you (or someone else) would like to take over this project and fix this bug, you're welcome to give me a link to your repo and I'll update this project's readme to add a pointer to your fork.
