When I use latest 5.1.1 I'm getting following error when using
change-set with DTABLE:
<?xml version = '1.0' encoding = 'UTF-8'?>
<change-set xmlns='http://drools.org/drools-5.0/change-set'

<add>
<resource source='file:DecisionTables.xls' type="DTABLE">
<decisiontable-conf input-type="XLS"
worksheet-name="Sheet1" />
</resource>
</add>

It's similar to JBRULES-2230. I reused solution from comments (on

patch. Can somebody apply to TRUNK?
