Hi,

When editing my source code in my DLTK based editor, I sometime have an exception in:

SourceModuleDocumentProvider.SourceModuleAnnotationModel.createPositionFromProblem

The exception is raised because the start position is greater than the documentLength which led to create a new Position with a negative length.

I suggest to modify the method and add the test below:

protected Position createPositionFromProblem(IProblem problem) {
	int start = problem.getSourceStart();
	if (start < 0)
		return null;
	int end = problem.getSourceEnd();
	if (end == 0 && start == 0) {
		return new Position(0, 0);
	}
	int length = end - start;
	if (length < 0)
		return null;
	int documentLength = fDocument.getLength();
>>>	if (start > documentLength)
>>>		start = documentLength;
	if(start + length > documentLength){
		length = documentLength - start;
	}
	return new Position(start, length);
}

I'm using DLTK 2.0.

I also filled the Bug 323825 in bugzilla.

Thanks,
Eric
