> CatchBuilder has a simple check for duplicate catch types. However, this check is never comprehensive as it still allows subtypes covered by supertypes, and covering that would be too costly; in addition, the "illegal" duplicate catch types are still valid `class` files. We should remove this duplicate catch type check, and compensate with documentation on the effects of duplicate types.
