This is "no mention at all"?

"Microsoft Access, also known as Microsoft Office Access, is a database 
management system from Microsoft that combines the relational Microsoft 
Jet Database Engine with a graphical user interface and software-
development tools." 
- the first sentence on the page I posted the URL for.

Of course, and the Java code exists. Jackcess is a Java class library 
that implements low level access to it and UCanAccess is a Java class 
library is a JDBC driver which delegates file access to Jackcess and SQL 
interpretation to the HSQLDB class library.

Indeed, and very many of the ODBC Access drivers connect to it, though it 
can be quite difficult to understand exactly what any particular driver 
does because descriptions provided by the authors and vendors of third 
party drivers are often anything but clear. I think MS-provided ODBC 
drivers use the JET Database Engine. 

And, since at least some JDBC Access drivers are wrappers for ODBC 
drivers, its safe to say that the same applies to them too. My original 
search, which was probably for "JDBC Access", only found a few commercial 
drivers with eye-watering prices and which failed to say whether or not 
they used the JET Database Engine to handle Access database files.
