+/**
+ * This class is similar to {@link SerializationUtils}. Unlike {@link
SerializationUtils} this class operates with
+ * {@code String}s and not byte arrays.
+ * <p>
+ * The main advantage of this utility is that it introduces an additional
operation after serialization and before
+ * deserialization. The operation consists in encoding/decoding the
serialized/deserialized data in Base64, so that
+ * data can be safely transmitted over the wire.

Couldn't we make this class public?
> Serializable attributes are not preserved by enqueue/dequeue on a JMS queue
> ---------------------------------------------------------------------------
>
> Key: JAMES-2167
> URL: https://issues.apache.org/jira/browse/JAMES-2167
> Project: James Server
> Issue Type: Bug
> Components: Queue
> Affects Versions: master
> Reporter: Tellier Benoit
> Priority: Major
>
> A call to toString breaks convertion for generic serializable attributes.
> The dequeued email will have only a toString version of it. We are expecting
> the exact same value, just deserialized.
> We should ensure the value of Serializable attributes gets preserved by
> enqueue/dequeue operations. We should add a unit test for this, and fix it.
