Following test fails if some special conditions are met:
org.switchyard.tests.VersionTest, module runtime

This test fails only if it is started with the following command in core folder.
mvn clean test. If I use mvn clean install, test will succeed. And if I use mvn clean test in folder runtime, test will succeed too.

There is a problem in class ManifestVersionFactory on line #51.

List<URL> urls = Classes.getResources(MANIFEST_NAME, getClass());

The variable urls does not contain some nedded resources => the classloader does not have some dependencies...
