Failing tests when using 'mvn package'

[cmahoneygtl]

Steps to reproduce:

1. Clone epublib master branch from github repository
2. Navigate to epublib folder
3. Navigate to epublib-core directory
4. Run 'mvn package' from shell

Note that there are 5 failing tests in the ResourcesLoaderTest class, all tests failing at line 166 and then 176. Appears to be an issue with verifying the expected array data (generated from IOUtil.toByteArray) against the actual array data. The maven package command fails as a result, meaning the latest version of this library can't be packaged for use in a project.
