plc4x hangs on query

We are trying to use plc4x (plc4j-driver-s7, version 0.7.0) to query data from a Siemens S7 PLC.

Here is a very simple example. When I run this it indefinitely hangs when executing the query.

String field = "%DB500.DBX4.0:BOOL";
connection
  .readRequestBuilder()
  .addItem("value-1", field)
  .build()
  .execute()
  .get();

I'm not 100% sure if the address is correct. Can I assume it would throw an error in case of unknown address? Or would it also just hang? Any tips how to trace this are highly appreciated.

Thanks a lot!
