But what is the advantage we are getting by implementing serializable
interface in DotNode Class ? Don't you think that it is something like a bug
? The objective of implementing serializable interface is simply "to
facilitate the serialization" but due to this very problem user can't able
to serialize that so i am not getting the point why it is implementing this
interface ?
Thanks,
Ganesh

Why do you need to serialized the parse trees? It would be better to
re-parse the string in order to get all the other non serializable
references anyhow.

java.io.NotSerializableException:
org.hibernate.hql.ast.HqlSqlWalker
On debugging i found that DotNode class has the reference of HqlSqlWalker
class and this class doesn't implement serializable interface.So the program
is throwing this exception. I think either the reference of HqlSqlWalker
should be declared as transient, or the HqlSqlWalker class itself should
also implement serializable interface to get the benefit of implementing
serializable interface by DotNode Class. Otherwise it is not worth to
implement serializable interface by DotNode class because ultimately we are
not able to serialize it in the current form .
Is it a bug or something else ??
