Subscribe() tries to cast S7Tag to S7SubscriptionTag and fails [Bug]:

[mrwhy-orig]

What happened?

Use the hello-world-plc4x-subscribe example and try to subscribe to a value change.

The subscription leads to following exception:

Exception in thread "Thread-0" java.lang.ClassCastException: class org.apache.plc4x.java.s7.readwrite.tag.S7Tag cannot be cast to class org.apache.plc4x.java.s7.readwrite.tag.S7SubscriptionTag (org.apache.plc4x.java.s7.readwrite.tag.S7Tag and org.apache.plc4x.java.s7.readwrite.tag.S7SubscriptionTag are in unnamed module of loader 'app')

I actually can't confirm this behavior on the current SNAPSHOT version, can it be closed?

Closing for no response.
