I20201228-1800: Bug 568263 - Primitive boxed just to call toString

A boxed primitive is allocated just to call toString(). It is more
effective to just use the staticform of toString which takes the
primitive value. So,


Replace...

With this...

new Integer(1).toString() Integer.toString(1)
new Long(1).toString() Long.toString(1)
new Float(1.0).toString() Float.toString(1.0)
new Double(1.0).toString() Double.toString(1.0)
new Byte(1).toString() Byte.toString(1)
new Short(1).toString() Short.toString(1)
new Boolean(true).toString() Boolean.toString(true)

Rank: Of Concern (16), confidence: High
Pattern: DM_BOXED_PRIMITIVE_TOSTRING
Type: Bx, Category: PERFORMANCE (Performance)
