Description

The following example works fine in 2.2.2:

import groovy.transform.CompileStatic

@CompileStatic
def extractInfo(String s) {
  def squareNums = s.findAll(/\d+/) { String num -> num.toInteger() }.collect{ Integer num -> num ** 2 }
  def wordSizePlusNum = s.findAll(/\s*(\w+)\s*(\d+)/) { _, String word, String num -> word.size() + num.toInteger() }
  [squareNums, wordSizePlusNum]
}

assert extractInfo(" ab 12 cdef 34 jhg ") == [[144, 1156], [14, 38]]

but in 2.3.0-rc-2 it gives the following errors:

4 compilation errors:
