[GROOVY-6802] CompileStatic: ListAssignment takes precedence over Coercion when statically compiling

• Type: Bug
• Status: Closed
• Priority: Major
• Resolution: Fixed

• Fix Version/s: 4.0.0-beta-2, 3.0.10, 2.5.22
• Component/s: Static compilation

Description

Observed on 2.2.2, but maybe affects all releases. To reproduce:

import groovy.transform.CompileStatic

@CompileStatic
class Foo {
  def static main(String[] args) {
    boolean b = [false]
    assert b
  }
}

fails, but should succeed given List should be coerced to Boolean via asBoolean()
