public class BooleanInstantiation
extends AbstractRule

Avoid instantiating Boolean objects; you can reference Boolean.TRUE, Boolean.FALSE, or call Boolean.valueOf() instead.

  public class Foo {
       Boolean bar = new Boolean("true");    // just do a Boolean
       bar = Boolean.TRUE;                   //ok
       Boolean buz = Boolean.valueOf(false); // just do a Boolean buz = Boolean.FALSE;
  }
