When editing my source code, 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 add this test:

	int documentLength = fDocument.getLength();
>>>>	if (start > documentLength)
>>>>		start = documentLength;
	if(start + length > documentLength){
		length = documentLength - start;
	}




Reproducible: Sometimes

Steps to Reproduce:
1. have an error marker on the end of the document
2. press the backspace rapidly to delete some part of code in the document body
