Hi!
In 5.0.c, I've count 13 of them, for me its not good.. Some contains new functionality other parts of alfresco depends on - for example, patched poi-xml contains AlfrescoPoiPatchUtils, and this class is used in PoiMetadataExtracter. I think this is is exactly what is called "bad architecture"
AFAIR great work was done to remove outdated functionality, but still myfaces*, spring-social* etc are in the libs, is this still used? antlr-2.7.7.jar and antlr-3.5.2.jar both in the libs…
BTW, I cant mark this thread as 5.0.c-related
