Applied 10.3.0a today, which was downloaded 2 April (after the
fix). Now, when choosing a time to deploy in Patch Management,
I get the following error:

org.hibernate.HibernateException: Found two representations of
same collection:
com.patchlink.sapphire.datamodel.PatchSignature.pa ckages

Do I need to do some DB maintenance or something?

TIA
