Scott M Stark commented on JBAS-1552:
-------------------------------------
The change in setting the serialVersionUID is sufficient if there are no serial
fields involved, however if there are, then the serialPersistentFields must be
conditionally set and readObject/writeObject methods added to control the names
of the fields to read/write. For example, the
javax.enterprise.deploy.spi.status.ProgressEvent changes include:
/** @since 4.0.2 */
static final long serialVersionUID;
// Constants -----------------------------------------------------
/**
* These field names match the j2ee 1.4.1 ri version names
*/
private static final ObjectStreamField[] serialPersistentFields;
private static final int STATUS_IDX = 0;
private static final int MODULE_ID_IDX = 1;
static
{
if (SerialVersion.version == SerialVersion.LEGACY)
{
serialVersionUID = 3097551795061550569L;
serialPersistentFields = new ObjectStreamField[] {
/** @serialField statuscode DeploymentStatus current deployment status
*/
new ObjectStreamField("status", DeploymentStatus.class),
/** @serialField targetModuleID TargetModuleID id of the event target
*/
new ObjectStreamField("moduleID", TargetModuleID.class)
};
}
else
{
// j2ee 1.4.1 RI values
serialVersionUID = 7815118532096485937L;
serialPersistentFields = new ObjectStreamField[] {
/** @serialField statuscode DeploymentStatus current deployment status
*/
new ObjectStreamField("statuscode", DeploymentStatus.class),
/** @serialField targetModuleID TargetModuleID id of the event target
*/
new ObjectStreamField("targetModuleID", TargetModuleID.class)
};
}
}
...
private void readObject(ObjectInputStream ois)
throws ClassNotFoundException, IOException
{
ObjectInputStream.GetField fields = ois.readFields();
String name = serialPersistentFields[STATUS_IDX].getName();
this.status = (DeploymentStatus) fields.get(name, null);
name = serialPersistentFields[MODULE_ID_IDX].getName();
this.moduleID = (TargetModuleID) fields.get(name, null);
}
private void writeObject(ObjectOutputStream oos)
throws IOException
{
// Write j2ee 1.4.1 RI field names
ObjectOutputStream.PutField fields = oos.putFields();
String name = serialPersistentFields[STATUS_IDX].getName();
fields.put(name, status);
name = serialPersistentFields[MODULE_ID_IDX].getName();
