I found the issue and reviewed the agent code and this has been fixed
in trunk. Edson si just fixing two failing tests, but as soon as the
build turns blue again grab the latest artifact builds and give it a
try:<br>

<pre wrap="">Mark,
I have some more information for you. The exception occurs when I issue:
agent.monitorResourceChangeEvents(true|false)
If I comment out that code, I don't get the exception, but I don't get
changes either. I tried it with both the Guvnor repository and with a
deployed package on the file system.
I won't have time to create the test you requested until the weekend. Let
me
know if you still want it.

<pre wrap="">Hmm that's not good. I have the following unit test:

Could you provide an update for new tests for detecting url changes?
When making the test you might find it easier to look at the previous
ruleagent tests:

I
think it is caused by the xml for the ChangeSet, but I'm using the

<pre wrap="">We haven't provided an XSD yet, so it'll provide schema validation
issues, those can be ignored.
