------------------------------------------

             Summary: CompileStatic doesn't call asBoolean
                 Key: GROOVY-10711
                 URL: https://issues.apache.org/jira/browse/GROOVY-10711
             Project: Groovy
          Issue Type: Bug
          Components: Static compilation
    Affects Versions: 4.0.3
            Reporter: Christopher Smith


This appears to be a duplicate of GROOVY-7807, but the test cases presented don't quite cover the behavior I see. I have a custom record class

{code}
@Immutable
@CompileStatic
@POJO
static class Result {
  String channel
  String thread

  boolean asBoolean() {
    println 'in asBoolean'
    false // for debugging
  }
}
{code}

When I call this from another class that is also statically compiled, the {{asBoolean}} method is not called.

{code}
if (!result) { // console prints diagnostic
  throw new NoChannelException() // block is not entered
}
{code}

{code}
        12: invokeinterface #136,  3          // load the Result
        17: astore_2
        18: aload_2
        19: pop
        20: aload_2
        21: dup
        22: ifnonnull     30
        25: pop
        26: iconst_0
        27: goto          32
        30: pop
        31: iconst_1
        32: ifne          39
        35: iconst_1
        36: goto          40
        39: iconst_0
        40: ifeq          58
        43: new           #138                // class NoChannelException
{code}

Both classes are in the same compilation unit, which may be relevant to the behavior, as {{@CompileStatic}} seems to correctly pull in {{asBoolean}}s from library code and extension method. However, in this case it's quite clearly disregarding the custom method and relying solely on a null check.
