Introduce `.impl` package for internal marshalling classes ---------------------------------------------------------- Key: ISPN-10326 URL: https://issues.jboss.org/browse/ISPN-10326 Project: Infinispan Issue Type: Sub-task Components: Core Reporter: Ryan Emerson Assignee: Ryan Emerson Priority: Major Fix For: 10.0.0.Beta5 Currently the `org.infinispan.marshall.core` and `org.infinispan.commons.marshall` packages expose a lot of internal classes which users should never attempt to use. To make this clearer, we should migrate internal classes to a `impl` package.
