Mockito 5: prepare for future JDK versions

For a while now, we have seen an increase in problems/incompatibilities with recent versions of the JDK due to our usage of JVM-internal API. Most notably, JDK 17 made some changes which are incompatible with the current subclass mockmaker. Therefore, to prepare for the future of JDK, we are making some core changes to ensure Mockito keeps on working.

Switch the default mockmaker to mockito-inline

Back in Mockito 2.7.6, we published a new mockmaker based on the "inline bytecode" principle. This mockmaker creates mocks manipulating bytecode equivalent within the original class such that its method implementations hook into the normal Mockito machinery. As a comparison, the subclass mockmaker generates "real" subclasses for mocks, to mimic the same behavior. While the approaches are similar, the inline mockmaker avoids certain restrictions that the JDK imposes. For example, it does not violate module boundaries (introduced in JDK 9, but more heavily used in JDK 17) and avoids the leaking of the creation of the subclass.

Massive thanks to community member @reta who implemented this change.

When should I still be using the subclass mockmaker?

There are legitimate remaining use cases for the subclass mockmaker. For example, on the Graal VM's native image, the inline mockmaker will not work and the subclass mockmaker is the appropriate choice. Additionally, if you would like to avoid mocking final classes, using the subclass mockmaker is a possibibility. Note however that if you solely want to use the subclass mockmaker to avoid mocking final, you will run into the above mentioned issues on JDK 17+. We want to leave this choice up to our users, which is why we will keep on supporting the subclass mockmaker.

If you want to use the subclass mockmaker instead, you can use the new mockito-subclass artifact (published on Maven Central along with all our other artifacts).

Update the minimum supported Java version to 11

Mockito 4 supports Java 8 and above. Similar to other open source projects, we are moving away from JDK 8 and to newer versions. The primary reason for moving away from JDK 8 is the increasing maintenance costs with keeping our own infrastructure working. Lately we have been running into more and more JDK 8 breakages. Additionally, while we want to support the newest JDK API's, our current solution to support both JDK 8 and newer versions causes issues with the SecurityManager. Since we want Mockito to work on the newest version and more and more businesses adopting JDK 11, we have decided to make the switch as well.

Massive thanks to community member @reta who implemented this change.

What should I do if I still run JDK 8?

For JDK 8 and below, you can keep on using Mockito 4. This is similar to if you are using JDK 6, for which you can keep on using Mockito 2. The changes in Mockito 5 (for now) are primarily focused on the latest JDK versions, which means the API differences between Mockito 4 and 5 are minimal. However, over time this will most likely widen, so we do recommend adopting JDK 11 in the future.

New type() method on ArgumentMatcher

One of our most used public API's for customizing Mockito is the ArgumentMatcher interface. The interface allows you to define a custom matcher, which you can pass into method arguments to provide more targeted matches. One major shortcoming of the ArgumentMatcher was the lack of varargs support.
