Description

To reproduce this, simply create a java file with only a comment in it. This is correct as per http://java.sun.com/docs/books/jls/third_edition/html/packages.html

SquidMavenCollector appears to be failing when analyzing a .java file that contains only a block comment. I am using Sonar 1.9, Hudson Plugin 1.0 and Java 1.5. This is the only project out of several that I am having problems with.
