Double brace initialization
Reports Double Brace Initialization.
Double brace initialization may cause memory leaks when used in a non-static context because it creates an anonymous class that will reference the surrounding object.
Compared to regular initialization, double brace initialization provides worse performance since it requires loading an additional class.
It may also cause failure of equals()
comparisons if the equals()
method doesn't accept subclasses as parameters.
In addition, before Java 9, double brace initialization couldn't be combined with the diamond operator since it was incompatible with anonymous classes.
