 Expected behaviour would be an error message expressing that there is no
 implicit conversion from "int" to "JValue".

+Problem also occurs if an implicit cast operator is added to JValue:
+
+class TestCase
+{
+    public struct JValue 
+    { 
+        int val; 
+        public JValue(int i) { this.val = i; }
+	public static implicit operator JValue(int i) { return new JValue(i); }
+    }
+    static void TriggerTheBug(params JValue[] args) {}
+    public static void Main() { TriggerTheBug(23); }
+}
+
+It disappears if 
+
+    public static void Main() { TriggerTheBug(23); }
+
+is replaced by
+
+    public static void Main() { TriggerTheBug(new JValue(23)); }
