SymmetricDS as a war on tomee server - symmetricds

Question

I am running SymmetricDS as a war on my tomee server and I am deploying two services, the master (pos-cc) and the slave (pos-dd). When the slave service starts, the following error appears:
ERROR org.jumpmind.symmetric.service.impl.RegistrationService - Unexpected error during registration: Parameter specified as non-null is null: method okhttp3.OkHttpClient$Builder.sslSocketFactory, parameter sslSocketFactory
java.lang.IllegalArgumentException: Parameter specified as non-null is null: method okhttp3.OkHttpClient$Builder.sslSocketFactory, parameter sslSocketFactory
symmetric-server.properties has these properties:

Does anyone know why this happens?

Answer 1

Can you set this in the engine files or if needed can be set as a system property for the Tomee server. The symmetric-server.properties is for the standalone Jetty deployment.
https2.enable=false
