Use Boolean constant values directly

From the SpotBugs report:

> NAB_NEEDLESS_BOOLEAN_CONSTANT_CONVERSION: Method needlessly boxes a boolean
> constant
>
> This method assigns a Boxed boolean constant to a primitive boolean variable,
> or assigns a primitive boolean constant to a Boxed boolean variable. Use the
> correct constant for the variable desired. Use
>
>
> boolean b = true;
> boolean b = false;
>
> or
>
>
> Boolean b = Boolean.TRUE;
> Boolean b = Boolean.FALSE;
>
> Be aware that this boxing happens automatically when you might not expect it.
> For example,
>
>
> Map statusMap = ...
>
> public Boolean someMethod() {
>     statusMap.put("foo", true);  //the "true" here is boxed
>     return false;  //the "false" here is boxed
> }
>
> has two cases of this needless autoboxing. This can be made more efficient by

> Map statusMap = ...
