In ManagerObjectFactory the String WEB_INF_CLASSES is hard coded to "/WEB-INF/classes" and is compared to a absolute path in line 54. bda.getId().contains(WEB_INF_CLASSES).

This is not suitable for Windows systems because of the separator (Windows uses '\') so the BeanManager cannot be initialized.
