Paul King updated GROOVY-9986:
------------------------------
Description:
The following program compiles (with @CompileStatic), although it shouldn't.
{code:java}
public class Main {
public static void main(String[] args) {
// Integer[] arr = new Integer[]{1, "str"}; // does not report error (see
GROOVY-9985)
Integer[] arr2 = [1, "fda"] as Integer[] // does not report error
}
}
{code}
As a result, an exception is thrown at runtime
{code:java}
Exception in thread "main"
org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast
object 'str' with class 'java.lang.String' to class 'java.lang.Integer'
