From the API docs
The boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string "true".

As you can see, anything else besides "true", including null generates false.

Because that's how the method works. If you pass anything other than a string containing the value "true" (ignoring case) the method returns false.

I agree. Here's the link:
