Documentation on primitives and wrappers is misleading

int i
m(i)

void m(long l) {     // This is the method that Java would call, since widening has precedence over unboxing.
  println "in m(long)"
}

void m(Integer i) {     // This is the method Groovy actually calls, since all primitive references use their wrapper class.
  println "in m(Integer)"
}

int i
m(i)

void m(int l) { // Groovy calls this method
  println "in m(int)"
}

void m(Integer i) {        
  println "in m(Integer)"
}

int i
m(i)

void m(long l) { // called by Groovy        
  println "in m(long)"
}

void m(Long i) {        
  println "in m(Long)"
}
