Description
In Room 2.3.0-alpha04 built-in enum support was added via a enum to string type converter. If a user already has a type converter Room should prioritize using user defined converters but there is a bug where if a one-way out converter (from Cursor to Enum) is defined, Room might incorrectly use the built-in one causing issues. This bug track such problem
It was fixed byhttps://android-review.googlesource.com/c/platform/frameworks/support/+/1524200 , but didn't make it into the 2.3.0-alpha04 release but instead it will be available in the next upcoming release.
