[API Updater] Internal error: Recursion detected while updating scripts (assembly index: 4) is thrown when updating scripts




Priority: 2Necessary for shipping a final release


Severity: 2Core functionality majorly impacted

Steps to reproduce:

1. Open attached project using Unity 5.6
2. API updater will ask to automatically update scripts, agree.
3. After project launches, check console for errors.

Expected results: No errors, scripts are updated.
Actual result: Internal error: Recursion detected while updating scripts (assembly index: 4)

The project itself was made with 5.4 beta 14 or somewhere close .
Opening the project and updating API works well with 5.5.0b11. If then opened with 5.6, everything seems to work fine.
API updater fails if opening project directly with 5.6.0b3

    This also happens with 2017.2 when trying to build for UWP. No warnings for obsolete API, but build fails. How do I know on which script exactly does the API updater fail?
