Description

I am trying to scan through my source using Antbuilder and parse the files to check if any annotations are present. I came across the following error while parsing a similar kind of file.

Please find the attached source to reproduce the error. Extract the zip to a folder and copy 1.6-beta-1 jar to that folder and type ant in that folder.
