Sometimes Analysis fails for SDF3 files when building the project. It might be related to https://yellowgrass.org/issue/Spoofax/903, but I am getting a different stacktrace, I think:

Internal error evaluating strategy editor-analyze

I have a workaround for the issue that posts a warning to the error log instead of a NPE. I can’t figure out how to properly fix this.
