Author: Guillaume Smet <guillaume.smet(a)gmail.com&gt; Date: 2016-06-17 (Fri, 17 Jun 2016) Changed paths: M core/src/main/java/org/hibernate/ogm/dialect/impl/BatchOperationsDelegator.java Log Message: ----------- OGM-1082 Include the exception message in the log when we batch several entity insertions and we end up with a TupleAlreadyExistsException. It's not perfect but it's far better than having the following message: Trying to insert an already existing entity: null which is quite misleading.
