Hi,

I have a simple hibernate project and try to use the hibernate console from Jboss Hibernate tools.  
The db connection (mysql) works, session factory and configuration are also fine.  
I open hql on atable and execute a query. This returns error:

`org.hibernate.type.SerializationException: could not deserialize.`

I searched on the web , but could not find anything that works.

Info on configuration and versions:  
Console configuration: Type: JPA, Hibernate Version 5.0 , database connection: ‘MySQL8015’,persistence unit, MySQL dialect.  
Eclipse 4.13  
JBoss Tools Hibernate 5.4.6v20191022  
Hibernate Version of project 5.3.6 - according to logging

when I select version 5.3.6 in console configuration it cannot connect to database - it return an exception saying ‘schema-validation: missing table xx’

Is there a solution to solve the serialization error with 5.0 ?

Thank you!
