Notes
(0125236) AugustoMauch (administrator) 2021-01-04 10:35	Leyre, I fixed the NullPointerException, but after that update.database does not finish, it seems that the XML parser it uses enters in an infinite loop when the log root is in debug mode. If the original purpose of changing the log root to debug was to check some problem in the update.database project, you might achieve the same result adding this line instead: <Logger name="org.apache.ddlutils" level="debug"/> Was that the purpose of changing the log level? Can you check if adding the line I mentioned achieves the same?

(0131041) plujan (manager) 2021-08-09 14:50	Updated as a design defect and moved back to New status
