Thank you for this report.

This could indicate an attempt to create a query using a closed EntityManager. If this is the case, a better error message should be produced.

Please make sure that you are using an open EntityManager.

Thanks, that was the problem

The error message was fixed in build 2.4.6_10. Thank you for this report.
