--------------------------------------
Summary: GroovyCastException when @CompileStatic and !in keyword
are used together
Key: GROOVY-10239
URL: https://issues.apache.org/jira/browse/GROOVY-10239
Project: Groovy
Issue Type: Bug
Components: Static compilation
Affects Versions: 3.0.9
Environment: macOs Big Sur 11.5.2
2,6 GHz 6-Core Intel Core i7
Java 11.0.11/16.0.1 (probably reproducible in other version)
Reporter: Rodolfo Yanke
Dear colleagues,
I've recently updated my projects from 3.0.8 to 3.0.9 and I started getting
some GroovyCastExceptions when trying to use *!in* keyword along with
CompileStatic annotation:
{code:groovy}
org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast
object 'true' with class 'java.lang.Boolean' to class 'Xyz'
{code}
We realised that it only works on 3.0.9 if we remove the CompileStatic
annotation(3.0.8 works with and without).
Here's an example of how to reproduce the exception:
{code:groovy}
import groovy.transform.CompileStatic
/**
* REMOVE @CompileStatic and the main method runs fine for both versions 3.0.8
and 3.0.9.
* 'Cannot cast object \'true\' with class \'java.lang.Boolean\' to class
\'MyEnum\''
* @CompileStatic only works with 3.0.8
*/
@CompileStatic
class Groovy309Error {
static void main(String[] args) {
def myObj = new MyObj(status: MyEnum.A)
List<MyObj> items = [myObj]
def newItems = items.findAll { it.status !in [MyEnum.B] }
println newItems
}
}
enum MyEnum {
A, B
}
class MyObj {
MyEnum status
}{code}
Please, forgive me if I missed something on the bug checklist but I think this
ticket belongs here.
Thank you in advance
