This adds a wee bit more information and corrects a method
reference -- it should not be #readResolve, but #writeReplace.

/**
* Base class for various bits of metadata attached to a {@link MetadataShardDataTreeSnapshot}. This class is not
* an interface because we want to make sure all subclasses implement the externalizable proxy pattern, for which
- * we need to force {@link #readResolve()} to be abstract.
+ * we need to force {@link #writeReplace()} to be abstract. We do that by making it final and exposing a protected
+ * {@link #externalizableProxy()} method.
* <p/>
* All concrete subclasses of this class should be final so as to form a distinct set of possible metadata. Since
* metadata is serialized along with {@link MetadataShardDataTreeSnapshot}, this set is part of the serialization format
