Description
About twice a day we get a NullPointerException in our build:

This comes at random times, and the next build doesn't fail.
I've googled for this failure and found nothing. I have this gut feeling that this may be caused by a concurrency issue in the maven-resources-plugin.
We got this error with maven-resources-plugin 2.4.3, and now with 2.5. Our maven version is 3.0.3.
We execute the build on TeamCity with the following parameters:
Goals: install Additional Maven command line parameters: -T 2C -e -P!releasex,integration -Dmaven.test.failure.ignore=true -Dmaven.test.error.ignore=true -Dmaven.test.haltafterfailure=false -Dmaven.junit.timeout=1000000 -DwarProject.packaging=jar
I'm seeing this issue as well with 2.4.3. It occurs randomly when doing a parallel build with Maven 3.x on JVM 1.6.
