Unnecessarily qualified static access

Reports usages of static members qualified with the class name.

Such qualification is unnecessary and may be safely removed.

Example:

class Foo {
  static void foo() {}
  static int x;

  void bar() {
    Foo.foo();
    System.out.println(Foo.x);
  }

  static void baz() { Foo.foo(); }
}

After the quick-fix is applied:

class Foo {
  static void foo() {}
  static int x;

  void bar() {
    foo();
    System.out.println(x);
  }

  static void baz() { foo(); }
}

Use the inspection options to toggle the reporting for:

Static fields access:
void bar() { System.out.println(Foo.x); }
Calls to static methods:
void bar() { Foo.foo(); }

Also, you can configure the inspection to only report static member usage in a static context. In this case, only static void baz() { Foo.foo(); } will be reported.
