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.
Note: this does not affect mockito-android nor testing on Android.
When should I still be using the subclass mockmaker?
