The server has an infinispan-defaults.xml file with some configuration templates that are available by default in the server and are automatically applied to all the caches defined in the server configuration XML.

These configuration templates change e.g. the lock acquisition timeout and state transfer timeout to match the old WildFly server's defaults, but these default values are not documented.

EmbeddedCacheManagerAdmin and RemoteCacheManagerAdmin also mention "the configuration marked as default on the container/server", but we don't really have that any more, as the default cache's configuration is no longer used as a template.
