>             Project: Maven 2.x Compiler Plugin
>          Issue Type: Bug
>    Affects Versions: 2.5, 2.5.1
>         Environment: MacOS 10.8.1 and 10.7.x
> Macintosh-3:~ clebertsuconic$ mvn -version
> Apache Maven 3.0.4 (r1232337; 2012-01-17 02:44:56-0600)
> Maven home: /work/maven/apache-maven-3.0.4

> I'm facing a NullPointerException on my project (HornetQ/master) when we update the maven-compiler
to 2.5.1 or 2.5. It all works fine with 2.3.2 and as soon as we update it we start having
these NPEs.
> It's funny that's only happening on MacOS for us while all our Linux Envs are working
fine. I'm not sure the root cause but it may be something that would eventually happen in
other environments as well.
> Steps to reproduce it:
> I don't have an isolated issue, but you can reproduce on my project:
> On a MacOS:
> git clone git://github.com/hornetq/hornetq.git
> edit the maven-compiler version to 2.5.1 on the main pom
> and use mvn package
