Overridable method called during object construction

Reports calls to overridable methods of the current class during object construction.

A method is called during object construction if it is inside a:

Constructor
Non-static instance initializer
Non-static field initializer
clone() method
readObject() method
readObjectNoData() method

Methods are overridable if they are not declared as final, static, or private. Package-local methods are considered safe, even though they are overridable. Such calls may result in subtle bugs, as object initialization may happen before the method call.

Example:

  class Parent {
    void someMethod() { }
  }

  class Child extends Parent {
    Child() {
      someMethod();
    }
  }
