Some sequences of highlighting causes AssertionFailedExceptions during editing or when trying to open the file. The exception when opening the file is also misleading. Stack traces below for both cases. I keep getting this error/stacktrace for a sequence of highlighting positions. And I tracked the problem down to when the MergingHighlightedPositionAcceptor is performing a merge. It performs this: Assert.isTrue(length >= 0); when the assert exception is triggered, so the merge must have computed a negative length. Here are the positions passed: WORKING SEQUENCE: offset: 7 length: 17 offset: 29 length: 5 offset: 30 length: 4 offset: 38 length: 13 offset: 39 length: 12 offset: 54 length: 12 offset: 70 length: 13

Pushed to master.
(In reply to comment #1) > Pushed to master. Thanks for the superfast turnaround!
And it works fine now.
