I use UML Designer for Eclipse 4.7.0 and got the following error while trying to add a new element to a diagram:
An error has occurred. See error log for more details. loader constraint violation: when resolving field "IS_DETACHMENT" the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the referring class, org/eclipse/sirius/business/internal/session/danalysis/DanglingRefRemovalTrigger, and the class loader (instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) for the field's resolved type, com/google/common/base/Predicate, have different Class objects for that type
Do I have to change some settings?
