Widlfly is using Configuration/GlobalConfiguration instances of one cache/cachemanager to create other cache managers.

Configuration/GlobalConfiguration are probably not designed to be shareable at this point in time. The builder classes should be sharable but sharing them would not have resolved the issue in ISPN-3698.

It probably makes sense to change marshaller to be a factory or lookup configuration to be able to create instances of marshaller when configuration is created.

ConfigurationBuilder/GlobalConfigurationBuilder classes are expected to be shareable.

Tests and verifications should be added.
