> Cassandra resolves pluggable extensions by class name from configuration,
> schema, and tooling
> inputs (cassandra.yaml, CQL DDL, JMX, schema/TCM, system properties, CLI
> tools). These names are
> loaded with an initializing `Class.forName(name)` and only checked against
> the expected extension
> type afterward. That ordering initializes the named class — running its
> static initializer and any
> side effects — before confirming it is the right type, so a mistyped or
> invalid class name is
> initialized before it is rejected. The type should be verified before
> initialization, so that only
> validated extension classes are initialized.
