Static collection
Reports static fields of a Collection type. While it's not necessarily a problem, static collections often cause memory leaks and are therefore prohibited by some coding standards.
Example:
public class Example {
static List<String> list = new ArrayList<>();
}
Configure the inspection:
Use the Ignore weak static collections or maps option to ignore the fields of the
java.util.WeakHashMaptype.
