Contents of the <filename>server.properties</filename> file. When using the API, you must ensure that the
contents of the file are base64 encoded. When using the AWS Management Console, the SDK, or the AWS CLI, the
contents of <filename>server.properties</filename> can be in plaintext.

<p>
The AWS SDK for Java performs a Base64 encoding on this field before sending this request to the AWS service.
Users of the SDK should not perform Base64 encoding on this field.
</p>
<p>
Warning: ByteBuffers returned by the SDK are mutable. Changes to the content or position of the byte buffer will
be seen by all objects that have a reference to this object. It is recommended to call ByteBuffer.duplicate() or
ByteBuffer.asReadOnlyBuffer() before using or reading from the buffer. This behavior will be changed in a future
major version of the SDK.
