Java
'Serializable' object implicitly stores non-'Serializable' object
Warning
New
Last modified: 03 December 2024 Reports any references to local non-Serializable
variables outside Serializable
lambdas, local and anonymous classes.
When a local variable is referenced from an anonymous class, its value is stored in an implicit field of that class. The same happens for local classes and lambdas. If the variable is of a non-Serializable
type, serialization will fail.
Example:
interface A extends Serializable {
abstract void foo();
}
class B {}
class C {
void foo() {
B b = new B();
A a = new A() {
@Override
public void foo() {
System.out.println(b); // warning
}
};
}
}

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
