This error type is reported in Java. It fires when an immutable collection is
|
|
returned from a method whose type is mutable.
|
|
|
|
```java
|
|
public List<String> getSomeList() {
|
|
ImmutableList<String> l = foo(...);
|
|
return l;
|
|
}
|
|
```
|
|
|
|
This can lead to a runtime error if users of `getSomeList` try to modify the
|
|
list e.g. by adding elements.
|
|
|
|
Action: you can change the return type to be immutable, or make a copy of the
|
|
collection so that it can be modified.
