[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-3239?page=c... ] pintail commented on HHH-3239: ------------------------------ I encountered the same problem having that exception in my logs. I placed a breakpoint when the NotSerializableException was thrown. I saw in my log another exception, which led me to this post: https://forum.hibernate.org/viewtopic.php?p=2407563 In one of the comments they mentioned to try to make the private default constructor to package protected. I also had a private default constructor. According to the documentation: http://docs.jboss.org/hibernate/stable/core/reference/en/html_single/#per... it is _recommended_ to make the default constructor at least package protected. It seems actually _needed_ instead of _recommende_. This solved the issue for me. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
