Re: [Hibernate] org.hibernate.hql.ast.tree.DotNode Implements Serializable but we can't serialize it

There is no piont.  However, it's not part of any public API.  There are probably more practical bugs to fix.

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,

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 ??
