Schema registry missing class

[aig787]

Kafka fails to start with embedded schema registry with the following error. Running the same code with EmbeddedKafkaConfig instead of EmbeddedKafkaConfigWithSchemaRegistry allows Kafka to start normally.

I also see this problem.

This may be related to incompatible versions of Jetty on your classpath. If you run something like sbt dependencyTree what's the ouptut for Jetty?
