this condition makes no sense :/

[alancutter (OOO until 2018), 2016/01/25 03:13:36]

I think you want:

if (!host || host->deprecation().isSuppressed(propertyID))
    return;

[nainar, 2016/01/25 03:48:24]

Fixed.

+        return;
+
+    String message = deprecationMessage(propertyID);
+    if (!message.isEmpty()) {
+        host->deprecation().suppress(propertyID);
+        frame->console().addMessage(ConsoleMessage::create(DeprecationMessageSource, WarningMessageLevel, message));
     }
