Description

Compile error: [Static type checking] - Cannot find matching method foo.Foo#vfunc(java.lang.String, java.lang.Integer).

If i is declared as int, then it compiles okay.
 

package foo
import groovy.transform.CompileStatic
@CompileStatic
class Foo {
    private void vfunc(String s, int... ints) {}
    void caller() {
        Integer i = 1
        vfunc('foo', i)
    }
}
