Clients cannot connect to Redis

[imbur]

Hi,
the packaged client.jar fails with an exception (see console output below) after trying to connect to Redis.

What I do:

0. Pull redis image: docker pull redis
1. Building the image: decking build thomas/models15
2. Creating the cluster: decking create main
3. Starting the cluster: decking start main
4. Examine the output: decking attach main

I also tried to rebuild the client.jar with maven, however, the generated jar in the org.kevoree.proto.models15.client/target folder seems to be a different "client" artifact, since it is not runnable in itself.

Thank you very much for your kind help in advance again!

Redis must be restarted after THP is disabled.
