Description

Fix broken routes that were incorrectly evicted from the route table. Any complex route that overlaps with the service document or metadata endpoint was being silently evicted. This most often happens using the parentheses route style. This was missed as it is no longer the default. New test coverage has been added to prevent future regression.

• Fixes Ambiguous default get with composite OData key #1138
