Unfortunately 5.0 has more incompatibilities than I expected. I removed the custom Strategy classes and deleted my database just to see what gets created with an absolutely fresh system and no special handling.

My project only has 5 Entities with many-many relationships between 4 of them so nothing too sophisticated. However, the schema check when creating the db fails after listing the "table not found" logs with the exception string that is literally "BIG PROBLEM" with no details on what is wrong I have not had any similar problems over the last year for any 4.x updates so will have to come back to this a while later

I expect the Spring community is going to deal with the issue soon as there have been a couple posts showing it was using the ImprovedNamingStrategy too
