Fix for JCLOUDS-655

First time committing to jclouds, let me know if there are any style guidelines I missed with this change.
Here are some examples.

    $ find . -name *ParserModuleTest.java
    ./jclouds/apis/chef/src/test/java/org/jclouds/chef/config/ChefParserModuleTest.java
    ./jclouds-chef/target/checkout/core/src/test/java/org/jclouds/chef/config/ChefParserModuleTest.java
    ./jclouds-labs/docker/src/test/java/org/jclouds/docker/config/DockerParserModuleTest.java
