Solution: Specify the parameter nullCatalogMeansCurrent=true in the mysql connection string,
<property name="url"><![CDATA[jdbc:mysql://localhost:3306/bboss?serverTimezone=UTC&useSSL=false&nullCatalogMeansCurrent=true]]> </property>

You may also need to specify the time zone serverTimezone parameter or other errors will be reported: here is specified as serverTimezone=UTC
