Unable to build with latest JDK

Hi Timber,

I just checked out this Timber repo and ran gradle test. However I'm seeing some robolectric issues.

My guess is your JDK is too new and restricts whatever Robolectric is doing. For now, you can use an older JDK. Long term we'll upgrade or eliminate Robolectric.

kapt is now broken on JDK 16 as well.
