    [ https://issues.apache.org/jira/browse/STANBOL-655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13289387#comment-13289387 ] 

Alessandro Adamou commented on STANBOL-655:
-------------------------------------------

It works on my installation if I replace 

Thread.currentThread().getContextClassLoader().loadClass(canonicalName);

with

Class.forName(canonicalName);

in the Rule adapter classes
