Description

I've seen a lot of issues related to this that were closed because they're a duplicate of MNG-2254 but I think the fix for MNG-2254 doesn't fix this issue.

I'm using maven 2.2.1 and the build failed when the UTF-8 POM begins with a BOM.

Here's the log when running clean install

Reason: Parse error reading POM. Reason: only whitespace content allowed before start tag and not \uef (position: START_DOCUMENT seen \uef... @1:1)  for project unknown at /home/marica/quick/pom.xml
