When batching the airtraffic database (air3 file) using a prepared statement to the server, a transaction rollback happens when the server is in autocommit mode. When not in autocommit mode, the loading process finishes successfully.
Also when commits are done inbetween the batches a transaction abort failure is returned. It feels like a commit in the process makes every next exec fail.

The attached java file can be compiled using:
% javac PrepareBatchCrash.java
And then run:
% java -cp .:$INSTALL_DIR/share/MonetDB/lib/monetdb-1.14-jdbc.jar PrepareBatchCrash "jdbc:monetdb://localhost/somedb?user=monetdb&password=monetdb" /var/tmp/air3

You can find the air3 file in /var/tmp on volund

This bug has to do with the cleanup of prepared handles on the server. It has been improved and fixed in the current development branch.
