Unnecessary 'return' statement

Reports return statements at the end of constructors and methods returning void. These statements are redundant and may be safely removed.

This inspection does not report in JSP files.

Example:

  void message() {
    System.out.println("Hello World");
    return;
  }

After the quick-fix is applied:

  void message() {
    System.out.println("Hello World");
  }
