I fixed the issue with this PR. I am going to test on one of our larger projects now.
If thats ok, I think this is good to merge in :) I will let you know.

I tested this on a project with 1k + ui.xml files and it works fine. I intentionally broke some of the ui.xml references and it showed the errors properly. Also then fixed them and it validated all correctly again, so it looks good from my side. Let me know if you need anything else.

Nice job!

I'll schedule to do a staging build tomorrow.

I am not sure, I'm not very experienced in the JDT api, but I moved that down to JLS3 which is java 5, just to be on the safe side. Retested everything and looks good.

[branflake2267]

Sounds good. No worries. I see the others are JLS3, do you think you could create a pull for that?

[seamusmac]

I already did. See #375 👍
