Description Andrey Loskutov

2018-10-27 04:01:53 EDT

On Java 11 SDK builds page we see following errors, all coming due the breaking JDK changes and "old" Mockito we are using.

This is most likely decribed in https://github.com/mockito/mockito/issues/1419 and https://github.com/mockito/mockito/issues/1483

Looks like 1419 issue was fixed in 2.19.1 version of Mockito (https://github.com/mockito/mockito/blob/release/2.x/doc/release-notes/official.md), we are still on 2.13 (at least the manifest says that), and Orbit also has 2.13.

Also 2.22.1 version claim to have better Java 11 support. 

Example stack:

Mockito cannot mock this class: class org.eclipse.e4.core.services.log.Logger. Mockito can only mock non-private & non-final classes. If you're not sure why you're getting this error, please report to the mailing list.
