How to reproduce:
1. Open the attached IIIIIAAAAABBBBB.zip project
2. Go to the Project window-> BUG_REPORT_FILES-> BugScene
3. Build and Run on Android device

Expected: Android class from an aar are loaded via AndroidJavaClass

Notes:
- Seems like regression, but I can't test earlier versions because of the thrown package errors
- See the logacat Terminal Saved Output.txt attached

Resolution Note (fix version 2019.3):

I need that fix for 2019.2.x, because 2019.3 does not contain the very fast (old) GUI Layer and I should write again the game UI.

Is there a workaround? or do I just have to install the latest unity?

When is this fix to arrive in a production version? between this bug and OpenGL shader bugs (this has since been fixed) we've been unable to compile a working build for Android since Sep 2019 (v2019.2.4), every version since has had show stopper issues. It'd be great if this could be stepped up and back ported to a 2019.2.x version as I'm quite concerned that 2019.3 is going to bring a fresh round of issues with it. Will the fix at least be shipped with the first production ready version of 2019.3? Sorry but having to wait 4 months to 'maybe' be able to compile a working android app is quite frustrating.
