Deploying multiple OSGi bundles with Dozer mapping files into JBoss Fuse/Fuse ESB has unexpected results

Issue

When there are multiple OSGi bundles containing Dozer mapping files, these will end up in exceptions such as:

Caused by: org.dozer.MappingException: Unable to locate dozer mapping file [OSGI-INF/dozer/*/Whatever-mapping.xml] in the classpath!

This happens randomly for random bundles, some of them get deployed fine, some not.
