Anonymous class variable hides variable in containing method

Reports fields in an anonymous class that are named identically to local variables or parameters of the containing method or lambda expression.

As a result of such naming, you may accidentally use the anonymous class field where the identically named variable or parameter from the containing method is intended.

A quick-fix is suggested to rename the field.

Example:

  class Test {
    public Test(String value) {
      Object foo = new Object() {
        private String value = "TEST";
        public void foo() {
          System.out.println(value); //the field is accessed, not the parameter
        }
      };
    }
  }
