      A workaround is to change the imports
      from:
      import nested.property.messages.*;

      to:
      import nested.property.messages.Message;
      import nested.property.messages.Payload;
      import nested.property.messages.PayloadType1;

      but in the real world this will get messy...

      The rule 

      Message(type == "PayloadType1", payload#PayloadType1.data.leaf == "5")

      gives the following Stack Trace:
