title	description
Immutable Cast	Detection of object cast from immutable types to mutable types. For instance, it will detect casts from `ImmutableList` to `List`, `ImmutableMap` to `Map`, and `ImmutableSet` to `Set`.

Detection of object cast from immutable types to mutable types. For instance, it will detect casts from ImmutableList to List, ImmutableMap to Map, and ImmutableSet to Set.

***DEPRECATED*** Unmaintained due to poor actionability of the reports.

Activate with --immutable-cast.

Supported languages:

• C/C++/ObjC: No
• Java: Yes

Casts flagged by this checker are unsafe because calling mutation operations on the cast objects will fail at runtime.
