Findbugs plugin throws FileNotFoundException for some of the files even though
the path is correct. Below is a snippet of the exception:

[FINDBUGS] Can't copy source file:
source=workspace/rel-1.1-may_2009/src/main/java/com/acn/repmgmt/euonlinerepagmt/business/ApplicationDataBD.java,

It doesn't fail the build and reports the statistics correctly. So, it is not a
big problem. But it is annoying to see so many exceptions in the log.
