[lworld] newInstance wrong return type Internal Error

Hotspot Internal Error with slowdebug build.

When using Reflection to invoke an inline class default constructor (aka static method).

----
import java.lang.reflect.Constructor;

public inline class Point2 {
    public static void main(String[] args) throws Exception {
        Constructor<?> c = Point2.class.getConstructor();
        c.newInstance();
    }

    public int x;
    public int y;
    public Point2 () {
        x = 10;
        y = 20;
    }
}

# guarantee(_is_return && t == _return_type) failed: return type does not match: 14 : 12
(modified to print actual, expected type - T_VALUETYPE vs T_OBJECT).
