Victor, you've increased the severity.  Does that mean you're reliably able to reproduce it?

No. But it happens more and more often - I should constantly close popups while working with JavaScript sources.

Javascript file to reproduce the error

This file is able to cause the error to occur.

Around 80% of the time if you place the cursor at the end of line 4, it will throw the exception.  If it doesn't throw it, then it will 100% of the time if I dirty the buffer (even adding a space and then deleting it).

Agree. But only in JavaScript project (Project Properties - Project Facets - JavaScript is checked). In usual Java project this script causes no errors.

Ah, I hadn't tested it out in a plain Javascript project.

In a plain Java project, sorry.
