I use an HSQLDB environment when my ivy Application is tested with Selenium Unit tests. The HSQLDB driver which is packed with ivy is the outdated version 1.8. With this version the concat() `concat()` and group_concat() `group_concat()` SQL functions are not (correctly) implemented and therefore some SQL statements can not be executed. I tried to use HSQLDB 2.3.2 by adding the jar *jre/lib/ext* folder and selecting the driver "other" within the "Databases Configuration Editor". But if I do that the Designer can no longer be started as the System-DB of the Designer relies on HSLDB 1.8. Is there any way to use a newer HSQLDB in my test environment?
