javaJdbc or jdbc?

I was mucking about a bit with the play-ebean example when I noticed this line in it:

While on the documentation, it says this:

https://www.playframework.com/documentation/2.6.x/JavaDatabase

To enable the database plugin add javaJdbc in your build dependencies :

libraryDependencies += javaJdbc

Is there a difference? Should the documentation be updated?
