Jesper Pedersen commented on WFLY-5570:
---------------------------------------

If <valid-connection-checker> or <check-valid-connection-sql> is defined, and there is no explicit value for <validate-on-match> or <background-validation>, then <validate-on-match> is turned on with a log statement

> Connection validation is now default

> In previous version the validation of connections was either off or set to be run in the background. In WF10RC2 connections are validated when they are fetched from the pool, the connection is validated before it is leased. This cause a huge contention on moderate to heavy db load and should not be the default behaviour.
