the jna version 4.5.2 is about 2 years old! It's definitely time to upgrade. Why has this not been done automatically?

It hasn't been done automatically as there has not yet been an appropriate time to move to a new major version of JNA. We upgraded to 4.5.0 in Spring Boot 2.0.0.M5 and since then we have kept up-to-date with the latest releases in the 4.5.x line. The natural point to upgrade to a new major version of JNA will be in Spring Boot 3.0 which is not yet planned. We can consider an upgrade in a 2.x release but we would need a compelling reason to do so. In the meantime, you can use the jna.version property to use a version of JNA that meets your needs.

We removed JNA as a managed dependency in 2.3 (See #20156). We might be able to upgrade our internal tools to use the newer version.
