[rules-users] Problem using KnowledgeAgent

[Dan Seaver]

I setup a KnowledgeAgent using the example code in the JavaDoc for
KnowledgeAgentFactory to access a compiled package in Guvnor. The package
runs fine, but changes to the package are not picked up. I believe this is
due to the ChangeSet notification thread being interrupted. But why?

Also, I'm getting some messages about failing to read schema document. I
think it is caused by the xml for the ChangeSet, but I'm using the example
from the JavaDocs.

Here's a snippet from the log:
