XJC non-transient non-serializable instance field data <p>After generating java classes I received:</p> <pre><code>public class myClass { @XmlElement(name = "Data", required = true) @XmlSchemaType(name = "date") protected XMLGregorianCalendar data; @XmlElement(name = "Time", required = true) protected XMLGregorianCalendar time; ......... </code></pre> <p>FindBugs warns that myClass defines non-transient non-serializable instance field data. Is it warning acceptable or need to fix? Thanks.</p>
