Look where TagData class is defined. Under Karaf you can try:
package:exports | grep org.apache.plc4x.camel
I suspect that you have org.apache.plc4x.camel.TagData type defined in
two places at runtime. It causes a friction when you break boundaries
and use TagData from one source in another context.
