Kadira endevent forced complete

Nobody has claimed this yet.

Ever since I added te arix:push package I've been seeing these weird errors/warnings. Have others seen these?

```

The report names arix:push and includes a Kadira trace, but no source file or test is identified. Start by reproducing the warning after adding arix:push, then compare the token lookup and insert sequence with a normal push-token update. Done means establishing a reproducible cause and documenting the affected behavior or a verified fix.
