java.lang.IllegalStateException: Uh oh! Event loop context executing with wrong thread!

[Luis Trigueiros]

Hi 

Does anyone knows the solution to this one I had a basic example working but when I changed my example to use a custom message codec registered in the event but I  started having this error.

In my example I am trying to pass messages using Google Protobuf message payloads.

java.lang.IllegalStateException: Uh oh! Event loop context executing with wrong thread! Expected null got Thread[globalEventExecutor-1-2,5,main]

Thank you, kindly

Ok, found that if the codec is registered with:

this.eventBus.registerDefaultCodec(Data.Request.class, new DataMessageCodec());

Then the problem does not happen.
