When user deploys app as a WAR in Tomcat, unless the tomcat-jdbc.jar
is in the app package, it will be found in the parent first and then
be unable to load the Driver class.
[Fixes#56720610] [bs-316] Tomcat non-embedded cannot load SQL driver class
A side effect is that spring-boot-starter-data-jpa needs
to include an aspectjweaver depdendency. Hope that doesn't
hurt anything else.
[Fixes#56780004]
