Please keep the discussion on the mailing list rather than commenting on the wiki (wiki discussions get unwieldy fast).

Motivation

According to the current code, the MAX_NUMBER_EXCEPTION_TO_REPORT is default 20 and not configurable. The problem is that the exception which is useful to users usually appears in the first exception, but if there are a lot of exceptions happened, users can only get the latest 20 exception messages, the first exception is gone.

Proposed Changes

Making the MAX_NUMBER_EXCEPTION_TO_REPORT configurable in REST API can solve this problem.
