Having problems with jmockit 1.45 and Junit 5.4

[ramses-gomez]

I just upgraded to the latest version of jmockit (1.45) and jUnit (5.4.0) and all the sudden all test were failing with a null pointer exception I checked and none of the objects injected by jmockit using annotations @tested, @injected and @mocked were being created, they were all null hence the null pointer exception I downgraded JUnit back to 5.3..2 and everything was working again.

Any suggestion with this?

As I explained in junit-team/junit5#1792 (comment), the JMockitInitialization class does not properly register JMockit's FakeExtensionRegistry which in turn never gets a chance to register the JMockitExtension.

Thus, JMockit's support for JUnit Jupiter simply never gets registered when using JUnit Jupiter 5.4+.

In junit-team/junit5#1792 (comment), I also outlined a workaround that works but is rather intrusive.

It's already fixed...
