Pattern: Unnecessary Boolean instantiation

Issue: -

Description

Checks for direct call to a Boolean constructor. Use Boolean.valueOf() or the Boolean.TRUE and Boolean.FALSE constants instead of calling the Boolean() constructor directly.

Also checks for Boolean.valueOf(true) or Boolean.valueOf(false). Use the Boolean.TRUE or Boolean.FALSE constants instead.

Here is an example of code that produces a violation:

def b1 = new Boolean(true)             // violation
def b2 = new java.lang.Boolean(false)  // violation
def b3 = Boolean.valueOf(true)         // violation
def b4 = Boolean.valueOf(false)        // violation
