Change artifact database v param to be type TEXT This is neccessary for large theme lists for example in the map. The 256 chars limit could easily be overtaken. I am using this for quite some time now and the upcoming version appears to be a good place to test this.

<?xml version="1.0" encoding="UTF-8" ?>
<datacage>
    <user>SA</user>
    <password/>
    <driver>org.h2.Driver</driver>
    <url>jdbc:h2:${artifacts.config.dir}/../datacagedb/datacage</url>
</datacage>
