I would like to kindly ask some help with regards to my weird problem in JPA 2.1 @ElementCollection/@CollectionTable mapping.
I have created the mapping below:
I was able to add, update, and read records from my Database. The issue arises when stop my local web app then start it again, and test the “FindAll” button that executes the select statement for getting the entire Employee in the table.
It hangs and there were logs exceptions that have been thrown, please see below:
I am not sure if I missed something or there are existing bugs in relation to this, but I already upgrade to the latest version of EclipseLink and MySQL Connector for Java.
I am hoping someone already encounter these particular anomalies when trying out these use case in JPA 2.1. I appreciate any help you could impart.
Thanks very much in advance!
